What is an ultrasound?
Ultrasound is a medical imaging technique that uses high-frequency sound waves to produce images of the inside of the body. It is a non-invasive and safe method that can be used to visualize organs, tissues, and structures in real-time.
During an ultrasound exam, a small handheld device called a transducer is placed on the skin or inside a body cavity. The transducer sends high-frequency sound waves into the body, which bounce off the tissues and organs and create echoes. These echoes are then detected by the transducer and converted into images by a computer.
Ultrasound can be used to diagnose a wide range of medical conditions, from pregnancy to heart disease to cancer. It is particularly useful for imaging soft tissues, such as the liver, pancreas, and muscles. It is also commonly used to guide biopsies and other medical procedures.
When was ultrasound invented?
Ultrasound technology was first developed in the early 20th century. In 1915, French physicist Paul Langevin and his assistant Constantin Chilowsky developed the first ultrasound transducer, which used piezoelectric crystals to convert electrical signals into sound waves.
In the following years, ultrasound technology was further refined and used in various applications, such as detecting flaws in metal and inspecting submarine hulls during World War II. In the 1950s and 1960s, medical researchers began exploring the use of ultrasound for medical imaging, and the first medical ultrasound images were produced in the late 1950s.
Since then, ultrasound technology has continued to evolve and improve, with advances in transducer design, image processing, and computer technology. Today, ultrasound is a widely used and essential tool in many areas of medicine.
How much does an ultrasound cost?
The cost of an ultrasound can vary widely depending on several factors, including the type of ultrasound exam, the facility or clinic where the exam is performed, and the geographic location.
In general, basic ultrasound exams can cost anywhere from $100 to $1000 or more, while more complex exams, such as a fetal echocardiogram or a breast ultrasound, can cost several thousand dollars. The cost of an ultrasound may also be affected by factors such as insurance coverage and discounts offered by the facility or clinic.
It's important to note that many insurance plans, including Medicare and Medicaid, typically cover the cost of medically necessary ultrasounds. However, patients may still be responsible for deductibles, copays, or coinsurance, which can also vary widely depending on the individual's insurance plan. It's always a good idea to check with your insurance provider or healthcare provider to understand your specific coverage and potential out-of-pocket costs.
How long does an ultrasound take?
The length of an ultrasound exam can vary depending on several factors, including the type of ultrasound being performed and the area of the body being examined. In general, most ultrasound exams take between 15 and 60 minutes to complete.
Some common ultrasound exams and their typical durations include:
- Abdominal ultrasound: 15-30 minutes
An abdominal ultrasound (sonogram) is an imaging test used to assess the organs and structures in the belly (abdomen). These include the:
- Liver
- Gallbladder
- Pancreas
- Bile ducts
- Spleen
- Kidneys
- Abdominal aorta
- Appendix
Ultrasound lets your healthcare provider easily see the abdominal organs and structures from outside the body. Ultrasound may also be used to assess blood flow to abdominal organs. [1]
- Pelvic ultrasound: 30-45 minutes
A pelvic ultrasound is a scan that looks at the organs and structures in your pelvic area. It lets your healthcare provider look at your:
- Uterus
- Cervix
- Vagina
- Fallopian tubes
- Ovaries
Your provider can also use Doppler ultrasound to look at how blood is flowing in certain pelvic organs. [2]
- Obstetric ultrasound: 30-60 minutes
Obstetric ultrasound uses sound waves to produce pictures of a baby (embryo or fetus) within a pregnant woman, as well as the mother's uterus and ovaries. It does not use ionizing radiation, has no known harmful effects, and is the preferred method for monitoring pregnant women and their unborn babies. A Doppler ultrasound study – a technique that evaluates blood flow in the umbilical cord, fetus or placenta – may be part of this exam. [3]
- Transesophageal echocardiogram (TEE): 45-60 minutes
A transesophageal echocardiogram (TEE) is a special type of echocardiogram. It is usually done when your doctor wants to look more closely at your heart to see if it could be producing blood clots. Like an echocardiogram, the TEE uses high-frequency sound waves (ultrasound) to examine the structures of the heart. A transducer (a unit that directs the sound waves) is placed in the esophagus (the pipe that connects the mouth to the stomach). The esophagus is close to the heart, so images from a TEE can give very clear pictures of the heart and its structures. [4]
It's important to note that the length of the exam can also be affected by factors such as the patient's body size, the complexity of the exam, and the need for additional images or measurements.
During the exam, the ultrasound technologist will apply a gel to the skin and use a handheld transducer to obtain images of the area being examined. The patient may be asked to change positions or hold their breath at certain points during the exam to help obtain better images. After the exam, the technologist will review the images and may ask the patient to wait briefly while additional images are obtained.

How does ultrasound work?
Ultrasound works by sending high-frequency sound waves into the body and then detecting the echoes that bounce back from the internal organs and tissues.
During an ultrasound exam, a handheld device called a transducer is placed on the skin or inserted into a body cavity. The transducer contains piezoelectric crystals that vibrate in response to electrical signals, producing sound waves. These sound waves travel into the body and bounce off the internal structures, creating echoes.
The echoes are then detected by the transducer and converted into electrical signals, which are sent to a computer that processes the information and creates images of the internal structures. The computer analyzes the echoes based on factors such as their strength, frequency, and time of arrival, and uses this information to create detailed images that can be viewed in real-time.
The images produced by ultrasound can provide information about the size, shape, and texture of internal organs and tissues, as well as the presence of any abnormalities or injuries. Ultrasound is particularly useful for imaging soft tissues, such as the liver, pancreas, and muscles, and is commonly used for imaging the fetus during pregnancy, as well as for diagnosing and monitoring a wide range of medical conditions.
What does an ultrasound show?
An ultrasound can show a wide range of internal structures, including organs, tissues, and blood vessels. The specific details that can be seen on an ultrasound will depend on the type of exam being performed and the area of the body being imaged.
Some of the information that an ultrasound can provide includes:
- The size, shape, and position of internal organs, such as the liver, pancreas, and kidneys
- The thickness and texture of tissues, such as the lining of the uterus or the wall of the bladder
- The presence of any abnormalities, such as cysts, tumors, or masses
- The flow and direction of blood in blood vessels and the heart
- The growth and development of a fetus during pregnancy, including the number of fetuses, the position of the placenta, and the development of internal organs and systems.
Ultrasound can also be used to guide medical procedures such as biopsies, amniocentesis, and fluid drainage. By providing real-time images of internal structures, ultrasound helps doctors to diagnose and monitor a wide range of medical conditions, and to plan and perform treatments as needed.
What are the different kinds of ultrasounds?
There are three main categories of ultrasound imaging, including: [5]
- Pregnancy ultrasound (prenatal ultrasound) - Healthcare providers often use ultrasound (often called prenatal or obstetric ultrasound) to monitor you and the fetus during pregnancy.
- Diagnostic ultrasound - Providers use diagnostic ultrasounds to view internal parts of your body to see if something is wrong or not working properly. They can help your provider learn more about what’s causing a wide range of symptoms, such as unexplained pain, masses (lumps) or what may be causing an abnormal blood test.
- Ultrasound guidance for procedures. - Providers sometimes use ultrasound to perform certain procedures precisely. A common use of ultrasound is to guide needle placement to sample fluid or tissue from: tendons, joints, muscles, cysts or fluid collections, soft-tissue masses, organs (liver, kidney or prostate).
What is a pelvic ultrasound?
(Ultrasound-Pelvis, Pelvic Ultrasonography, Pelvic Sonography, Pelvic Scan, Lower Abdomen Ultrasound, Gynecologic Ultrasound, Transabdominal Ultrasound, Transvaginal Ultrasound, Endovaginal Ultrasound)
A pelvic ultrasound is a medical imaging test that uses high-frequency sound waves to create images of the internal structures in the pelvic region, including the uterus, ovaries, fallopian tubes, bladder, and prostate gland in men.
During a pelvic ultrasound, a transducer is placed on the skin of the lower abdomen or inserted into the vagina (for women) or rectum (for men). The transducer emits sound waves that pass through the pelvic structures and bounce back to create echoes, which are then converted into images by a computer.
Pelvic ultrasounds can be performed for a variety of reasons, such as to investigate pelvic pain, abnormal uterine bleeding, or infertility in women, or to diagnose prostate problems or detect abnormalities in the male reproductive system. In women, a pelvic ultrasound can also be used to monitor pregnancy, detect ovarian cysts or tumors, and evaluate the thickness and texture of the uterine lining.
Pelvic ultrasounds are non-invasive and typically take around 30-45 minutes to complete. They are considered safe and are usually painless, although some patients may experience mild discomfort or pressure during the exam. The images produced by a pelvic ultrasound can provide important information for diagnosing and treating a wide range of medical conditions.
What is ultrasound used for?
Ultrasound helps diagnose the causes of pain, swelling and infection in the body's internal organs and to examine an unborn child (fetus) in pregnant women. In infants, doctors commonly use ultrasound to evaluate the brain, hips, and spine. It also helps guide biopsies, diagnose heart conditions, and assess damage after a heart attack. Ultrasound is safe, noninvasive, and does not use radiation. [6]
- Imaging internal structures: Ultrasound can produce detailed images of internal organs, tissues, and blood vessels, allowing doctors to diagnose a wide range of medical conditions.

A renal ultrasound is a medical imaging test that uses high-frequency sound waves to create images of the kidneys and surrounding structures. The test is non-invasive and painless, and it provides valuable information about the size, shape, and position of the kidneys, as well as the presence of any abnormalities or blockages.
During a renal ultrasound, a small handheld device called a transducer is moved over the skin of the abdomen, emitting sound waves that bounce off the kidneys and create images on a computer screen. The test typically takes about 30 minutes to complete and does not require any special preparation or recovery time.
Renal ultrasound is commonly used to evaluate conditions such as kidney stones, cysts, tumors, and infections. It can also be used to monitor the progress of certain kidney treatments or procedures, such as dialysis or kidney transplant surgery.
How early can an ultrasound detect pregnancy?
An ultrasound can typically detect pregnancy as early as 5-6 weeks after the last menstrual period. At this stage, a transvaginal ultrasound is typically used, which involves inserting a small, lubricated wand into the vagina to obtain images of the uterus and developing fetus.
The transvaginal ultrasound can detect a gestational sac, which is a fluid-filled structure that develops in the uterus after fertilization. A fetal heartbeat can sometimes be detected at this stage as well.
However, it's important to note that the timing of when a pregnancy can be detected on ultrasound can vary depending on factors such as the woman's menstrual cycle, the accuracy of the estimated date of conception, and the sensitivity of the ultrasound equipment. In some cases, it may be necessary to wait until 7-8 weeks after the last menstrual period to confirm a pregnancy on ultrasound.
What does an abdominal ultrasound show?
An abdominal ultrasound is a medical imaging test that uses high-frequency sound waves to produce images of the organs and structures in the abdomen. It is a non-invasive and painless procedure that is often used to diagnose various medical conditions.
During an abdominal ultrasound, a handheld device called a transducer is placed on the abdomen and moved around to capture images of the internal organs. The images produced by the ultrasound can provide valuable information about the organs and structures in the abdomen.
Some of the things that an abdominal ultrasound can show include:
- Liver: The ultrasound can show the size, shape, and texture of the liver, as well as any abnormalities such as cysts or tumors.
- Gallbladder: An ultrasound can show the size and shape of the gallbladder, and can detect the presence of gallstones or other abnormalities.

What does a blocked carotid artery look like on ultrasound?
A blocked carotid artery can be detected on ultrasound by visualizing the blood flow through the artery. The ultrasound technician will use a handheld device called a transducer to send high-frequency sound waves through the skin, which bounce back off the blood vessels and create images that can be seen on a computer screen.
In the case of a blocked carotid artery, the ultrasound may reveal a narrowed or blocked segment of the artery, with little or no blood flow through it. The blocked area may appear as a dark, shadowy region on the ultrasound image.
The ultrasound may also show signs of plaque buildup within the artery, which can appear as bright, reflective areas on the ultrasound image. Plaque buildup is a common cause of carotid artery blockages and can increase the risk of stroke.
Overall, an ultrasound is a non-invasive and effective way to detect carotid artery blockages, allowing doctors to diagnose the problem and recommend appropriate treatment options to reduce the risk of stroke.
What does a blood clot look like on an ultrasound?
A blood clot can be detected on an ultrasound by visualizing the blood flow and looking for areas where the flow is obstructed. The appearance of a blood clot on an ultrasound will depend on the size and location of the clot.
If the clot is large and located near the skin's surface, it may appear as a dark, shadowy area on the ultrasound image. The clot may also cause the vein to become enlarged and distorted.
If the clot is located deeper in the body, such as in the leg veins, the ultrasound may show reduced or absent blood flow in the affected vein. The clot may appear as a hypoechoic or anechoic region, which means that it reflects little or no ultrasound waves.
In addition to visualizing the clot, ultrasound can also be used to assess the overall health of the vein and the surrounding tissues. This can help doctors determine the best course of treatment, which may include blood-thinning medications, compression stockings, or surgery.
Overall, ultrasound is a non-invasive and safe way to detect blood clots, allowing doctors to diagnose the problem quickly and accurately and recommend appropriate treatment options to prevent complications such as pulmonary embolism.
What does an ultrasound of the heart show?
An ultrasound of the heart, also called an echocardiogram, is a medical imaging test that uses high-frequency sound waves to create detailed images of the heart and its structures. It is a non-invasive and painless procedure that allows doctors to assess the structure and function of the heart.
What are the different types of echocardiogram?
There are several types of echocardiogram. Each one offers unique benefits in diagnosing and managing heart disease. [7] They include:
- Transthoracic echocardiogram.
- Transesophageal echocardiogram.
- Exercise stress echocardiogram.
During an echocardiogram, a technician will place a small handheld device called a transducer on the chest, which emits sound waves that bounce off the heart and create images on a computer screen. The test typically takes about 30-45 minutes to complete, and it can provide a wealth of information about the heart's health and function.
An echocardiogram can show several things, including:
- The size and shape of the heart: This can help doctors determine if the heart is enlarged or has an abnormal shape.
- The movement and function of the heart's chambers and valves: This can help doctors assess how well the heart is pumping blood and whether there are any problems with the heart's valves.
- The thickness and movement of the heart muscle: This can help doctors determine if there is any damage to the heart muscle or if it has become thickened due to a condition like hypertension.

Overall, a thyroid ultrasound is a valuable tool for diagnosing and monitoring thyroid conditions such as goiter, thyroid nodules, and thyroid cancer. It can also be used to evaluate the effectiveness of certain thyroid treatments or procedures, such as thyroidectomy or radioactive iodine therapy.
When is the best time to get a 3D ultrasound?
A 3D ultrasound is a type of medical imaging test that uses high-frequency sound waves to create three-dimensional images of a fetus in the womb. The best time to get a 3D ultrasound is typically between 26 and 32 weeks of pregnancy.
During this time, the fetus has developed enough that its facial features are visible and well-formed, but there is still enough room in the uterus to obtain clear images. It's important to note that 3D ultrasounds are not typically recommended for diagnostic purposes, as they are primarily used for fetal bonding and to provide a more detailed view of the baby's features.
It's important to discuss the timing and necessity of a 3D ultrasound with your healthcare provider, as they can provide guidance based on your individual pregnancy and medical history.
What is the difference between an ultrasound and a sonogram?
Technically speaking, there is no difference between an ultrasound and a sonogram. Both terms refer to the same medical imaging test that uses high-frequency sound waves to create images of the body's internal structures.
However, in common usage, the term "ultrasound" is often used to refer to the technology and equipment used to perform the test, while "sonogram" is often used to refer to the actual images or pictures that are produced.
So, in summary, both terms are essentially interchangeable, but "ultrasound" tends to refer to the medical test itself, while "sonogram" tends to refer to the resulting images.
How to prepare for an ultrasound?
The preparation for an ultrasound may vary depending on the type of ultrasound and the area of the body being examined. Here are some general guidelines to prepare for an ultrasound:
- Follow any specific instructions provided by your healthcare provider: Your healthcare provider may provide you with specific instructions to follow before your ultrasound. It's important to follow these instructions carefully to ensure the best possible results.
- Wear comfortable, loose-fitting clothing: Wear comfortable clothing that allows easy access to the area of the body being examined. For example, if you're having an abdominal ultrasound, you may be asked to wear a loose-fitting shirt or blouse and pants or a skirt without a lot of zippers, buttons, or other metal objects.
- Avoid eating or drinking for a specific period before the test: Depending on the type of ultrasound, you may be asked to avoid eating or drinking for several hours before the test. This is because a full stomach or bladder can interfere with the results of the test.
- Drink water: In some cases, you may be asked to drink water before the test, especially if you're having an abdominal or pelvic ultrasound. A full bladder can help improve the clarity of the images.
- Remove jewelry and metal objects: You may be asked to remove jewelry or other metal objects that could interfere with the test, such as watches, necklaces, or piercings.
- Discuss any medications with your healthcare provider: Inform your healthcare provider of any medications you are taking, especially blood thinners or medications that affect blood clotting.
It's important to talk to your healthcare provider if you have any questions or concerns about how to prepare for your ultrasound.
What is a doppler ultrasound?
An ultrasound Doppler is a type of medical imaging test that uses high-frequency sound waves to measure the speed and direction of blood flow in the body's blood vessels. The test is named after Austrian physicist Christian Doppler, who first described the phenomenon of frequency shift in sound waves caused by the motion of a source relative to an observer.
During an ultrasound Doppler test, a special handheld device called a transducer is placed on the skin over the area being examined. The transducer emits sound waves that bounce off the moving blood cells and are picked up by the transducer as they return. The ultrasound machine then uses the information from the returning sound waves to create images of the blood flow in real-time and calculate the speed and direction of the blood flow.
Ultrasound Doppler tests are commonly used to evaluate blood flow in the arteries and veins of the body, including the carotid arteries in the neck, the aorta in the abdomen, and the veins in the legs. The test can detect areas of blockage or narrowing in the blood vessels, as well as abnormalities in blood flow caused by conditions such as deep vein thrombosis (DVT), varicose veins, or peripheral artery disease (PAD). It can also be used to monitor the success of certain medical treatments, such as balloon angioplasty or stenting.
This test may be done as an alternative to more-invasive procedures, such as angiography, which involves injecting dye into the blood vessels so that they show up clearly on X-ray images. [9]
A Doppler ultrasound may help diagnose many conditions, including:
- Blood clots
- Poorly functioning valves in your leg veins, which can cause blood or other fluids to pool in your legs (venous insufficiency)
- Heart valve defects and congenital heart disease
- A blocked artery (arterial occlusion)
- Decreased blood circulation into your legs (peripheral artery disease)
- Bulging arteries (aneurysms)
- Narrowing of an artery, such as in your neck (carotid artery stenosis)
Ultrasound vs. X-Ray: Which Imaging Technique Is Right for You?
Ultrasound and X-ray are two common imaging techniques that are used for different purposes. The choice of which imaging technique to use depends on the specific medical condition being evaluated and the information that needs to be obtained.
Here are some key differences between ultrasound and X-ray:
- Technology: Ultrasound uses high-frequency sound waves to create images of the internal structures of the body, while X-rays use low doses of radiation to create images of bones and certain soft tissues.
- Safety: Ultrasound is generally considered to be very safe, as it does not use ionizing radiation. X-rays, on the other hand, use ionizing radiation and carry a small risk of causing cancer or other health problems, particularly with frequent or high-dose exposure.
- Types of structures imaged: Ultrasound is particularly useful for imaging soft tissues, such as muscles, organs, and blood vessels. X-rays are best for imaging bones and certain soft tissues, such as the lungs.
- Uses: Ultrasound is commonly used to evaluate pregnancy, abdominal pain, and blood flow in the arteries and veins. X-rays are used for evaluating broken bones, lung problems, and certain cancers.
- Limitations: Ultrasound has limitations in terms of depth of penetration, so it may not be able to provide clear images of structures that are deep in the body. X-rays have limitations in terms of the level of detail they can provide.
In summary, ultrasound and X-ray are both valuable imaging techniques, but they are used for different purposes and have their own advantages and limitations. Your healthcare provider will determine which imaging technique is appropriate for your specific medical condition based on your symptoms, medical history, and other factors.
The Future of Ultrasound: Advancements and Innovations in Medical Imaging
