What is Doppler Ultrasound

Doppler ultrasound is a special type of ultrasound which is used to look at blood flow. A Doppler ultrasound machine has a hand-held scanner which is connected to a computer. It uses sound waves to make pictures of the blood flow in your major arteries and veins. If you want to know the specifications and prices of Doppler ultrasound, please contact us!

Advantage of Doppler Ultrasound

Digital Ultrasound Fetal Doppler for Pregnancy

Non-invasive

Doppler ultrasound is a non-invasive imaging technique that does not require the insertion of instruments or the use of anesthesia. It eliminates the need for surgical procedures, reducing the risks and discomfort associated with invasive methods.

Generally Painless

The procedure is usually painless for the patient. Unlike some invasive diagnostic methods, Doppler ultrasound involves the use of high-frequency sound waves, which are not painful and do not cause discomfort during the examination.
Does not use Radiation
Doppler ultrasound does not involve the use of ionizing radiation, making it a safer option compared to imaging techniques such as X-rays or CT scans. This absence of radiation exposure is particularly beneficial for pregnant women and individuals who need frequent or repeated imaging studies.

Can Show if You Have Any Blocked Arteries in Your Neck, Arms, and Legs

Doppler ultrasound can detect and visualize the blood flow in arteries, providing valuable information about potential blockages or restrictions. This is crucial for diagnosing conditions such as atherosclerosis, where plaque buildup may impede blood flow in the arteries of the neck, arms, or legs.

Can Show if You Have Any Blood Clots in The Veins in Your Legs

Doppler ultrasound is effective in identifying blood clots (deep vein thrombosis) in the veins of the legs. By assessing blood flow and detecting abnormal patterns, healthcare professionals can diagnose and monitor the presence of clots, helping to prevent serious complications like pulmonary embolism.

Can Show the Amount and Speed of Blood Flow in Your Veins and Arteries

Doppler ultrasound provides real-time information about the velocity and volume of blood flow in veins and arteries. This data is crucial for assessing the overall health of the circulatory system, identifying abnormalities, and evaluating the effectiveness of blood circulation in specific areas of the body.

Can Be Used Instead of Some More Invasive Procedures

Doppler ultrasound is a valuable alternative to certain invasive procedures, such as angiography. It allows healthcare providers to gather essential diagnostic information without the need for surgery or more invasive interventions, reducing the associated risks, recovery time, and patient discomfort.

What is the Use of Doppler Ultrasound?

Sonography is a useful way of evaluating the body's circulatory system. Vascular ultrasound is performed to:
●Help monitor the blood flow to organs and tissues throughout the body.
●Locate and identify blockages (stenosis) and abnormalities like plaque or emboli and help plan for their effective treatment.
●Detect blood clots (deep venous thrombosis (DVT) in the major veins of the legs or arms.
●Determine whether a patient is a good candidate for a procedure such as angioplasty.
●Evaluate the success of procedures that graft or bypass blood vessels.
●Determine if there is an enlarged artery (aneurysm).
●Evaluate varicose veins.

In children, ultrasound is used to:
●Aid in the placement of a needle or catheter into a vein or artery to help avoid complications such as bleeding, nerve injury or pseudo-aneurysm (abnormal outpouching of an artery with the risk of rupture).
●Evaluate a connection between an artery and a vein which can be seen in congenital vascular malformations (arteriovenous malformations or fistula) and in dialysis fistula.
If a line is placed in an artery or vein of the legs or arms, there is a much higher chance of developing a clot around it due to the smaller vessel size (especially in infants and young children). In some instances, a clot can form in the arm or in the left leg with the latter extending into major veins in the abdomen.

Doppler ultrasound helps the doctor to see and evaluate:
●Blockages to blood flow (such as clots)
●Narrowing of vessels
●Tumors and congenital vascular malformations
●Reduced or absent blood flow to various organs, such as the testes or ovary
●Increased blood flow, which may be a sign of infection

Home Use Curve Rechargeable Ultrasound Fetal Doppler

How to Use Doppler Ultrasound?

Depending on the reason for the test, you may lie on your back or side on an exam table, or you may sit up.
During the test:
●Applies a small amount of gel to your skin. The gel helps the sonographer glide a small probe over the skin. It also helps sound waves travel.
●The transducer sends painless sound waves through your skin into your body. The sound waves are high frequency and you won't hear them.
●The sound waves reflect off the moving blood cells, causing the pitch of the sound waves to change. You may hear a whooshing sound from the ultrasound machine.
●The transducer detects changes in the sound wave.
●A machine records the sound wave changes and converts them into images or graphs for your provider to review.
●The sonographer cleans the gel from your skin at the end of the test.

Types of Doppler Ultrasound

"Bedside" or Continuous Wave Doppler

This type uses the change in pitch of the sound waves to provide information about blood flow through a blood vessel. The doctor listens to the sounds made by the transducer to assess the blood flow through an area that may be blocked or narrowed. This type of ultrasound can be done at the bedside in the hospital. It uses a portable machine that can quickly check the extent of blood vessel damage or disease.

Duplex Doppler

This test uses standard ultrasound methods to make a picture of a blood vessel and the organs around it. A computer turns the Doppler sounds into a graph. This graph helps to show the speed and direction of blood flow through the blood vessel.

Colour Doppler

Colour Doppler uses standard ultrasound methods to make a picture of a blood vessel. A computer changes the Doppler sounds into colours that are overlaid on the image of the blood vessel. These colours show the speed and direction of blood flow through the vessel. Power Doppler is a special type of colour Doppler. Power Doppler can get some images that are hard or impossible to get using standard colour Doppler. Power Doppler is most often used to look at blood flow through vessels within solid organs.

Doppler Ultrasound Techniques for Listening to Fetal Heartbeat

Compare Heart Rate Ranges
Sometimes a mother hears a heartbeat and assumes it's her baby's when it's actually her own. So how can you tell?
Comparing normal heart rate ranges for fetuses and adults can help you determine which noise you're picking up. Keep the ranges below in mind.
●Normal Adult Heart Rate: 60-80 bpm.
●Normal Fetus Heart Rate: 120-180 bpm.
If the heartbeat you detect is in the range of a normal adult heartbeat, you're probably picking up your own heart. If it falls in the normal fetus range, the fetal doppler is likely picking up your baby.
Fetus heartbeats can vary widely. That's because the heartbeat changes as they develop. For example, if you're able to detect your baby at 9 weeks, you may notice a higher reading, about 170 bpm. By week 14, it's likely dropped to around 150 bpm.

Listen for "Whooshing" Placenta Noise
It's common to mistake the sound of your placenta for your baby's heartbeat.
To know if it's placenta making the noise, listen to it carefully. Women often describe the sound of placenta on a fetal doppler as:
●Whooshing noise.
●Sounds like wind blowing through trees.
●"Wowowowow" sound.

Listen for "Galloping" Heartbeat
While placenta can sound like wind, your baby's heartbeat has another distinct noise.
Some people compare the sound of a fetal heartbeat through a fetal doppler to:
●The sound of galloping horses.
●Similar to the noise of jumping rope very rapidly.

Compare With Noises From Videos
One of the best ways to discern noises from a pocket fetal doppler is to watch other people use them. Spend time getting used to what a fetal heartbeat sounds like. Learn how other body noises sound different.
To hear what a fetal heartbeat might sound like at a specific week of pregnancy, search "fetal doppler X week" on YouTube (be sure you're using a reliable source who's detecting the correct noise!).

Listen for Echoing
If you're pregnant with a single baby and think you hear two heartbeats, you're likely hearing echoes. Some people hear two noises and think they're pregnant with twins. Unless your doctor has confirmed multiple pregnancies, it's likely you're hearing the echo of your single baby.

Watch Your Doctor Use Their Fetal Doppler
During your next prenatal checkup, watch how your doctor uses their fetal doppler. Although they'll have a different medical device, the basics will be similar. Watch how they rock the probe and cover your belly until they find the heartbeat. Then pay close attention to what a fetal heartbeat sounds like. If you have questions, ask. You might also simply ask, "Can you walk me through the steps of using the fetal doppler and everything you're detecting?"
If your doctor or midwife is willing, you can also ask them to help you use your own doppler. This can be helpful if you're feeling confused or unsure.

Practice & Accept You're Not a Pro
One of the best tips for discerning your baby's heartbeat is to practice. Over time, you'll become more familiar with the noise and will be able to differentiate between the heartbeat and body noises.
With that being said, no matter how much practice you have, you're not a professional. While you can listen to your baby's heartbeat between appointments, it will never replace checkups. Resist the urge to self-diagnose and instead talk to your doctor or emergency care about any concerns.

Other Important Fetal Doppler Heartbeat Tips
To help you detect your baby's heartbeat on a fetal doppler, try these suggestions:
●Use fetal doppler on a full bladder (helps push your uterus out of the pelvic cavity).
●Consider using a 2MHz probe if Overweight (get a 2MHz probe here).
●Cheap fetal dopplers produce more feedback and make it difficult to listen (use a reliable brand!).
●Be generous with ultrasound gel to avoid too much feedback.
●Clean probe after every use to avoid build-up that can produce feedback.
●If you can't pick up a heartbeat, try again in the next few days.

Frequently Asked Questions

Q: How often should a Doppler Ultrasound be performed?

A: Ideally, Doppler studies should be repeated every 6–12 months (or earlier if clinically indicated). In practice, the frequency will be guided by local availability and resources.

Q: How long does a Doppler Ultrasound last?

A: You may hear the sound of the blood flowing through your blood vessels. When your ultrasound is finished the staff will give you something to clean off the gel and ask you to wait while they check the pictures. A Doppler ultrasound usually takes about 30 minutes to an hour, including time taken to get ready.

Q: Do you need to drink water before use Doppler Ultrasound?

A: If ultrasound pelvis is also being done, for female patients, please drink 32 oz of water one hour before the scan. You can go to the bathroom to relieve yourself, as long as you keep drinking water. Male patients do not need to have a full bladder.

Q: How should overall Doppler Ultrasound gain be adjusted?

A: To optimize the gain setting, the gain should be increased so that the color on the image display becomes visible outside of the boundaries of the vessel wall. A subsequent decrease in gain until all of the color specks outside of the vascular wall are removed will ensure proper adjustment of this setting.

Q: Is it okay to use Doppler Ultrasound everyday?

A: Using it for a few minutes once a week shouldn't cause any harm to your baby. At-home fetal dopplers can also be potentially harmful because they can give you a false sense of reassurance, according to the United Kingdom's National Health Service (NHS).

Q: Can you overuse a fetal Doppler Ultrasound?

A: However, the heat that they generate can pose a risk to the baby, so it is reasonable to assume that overusing them can cause a problem. If a person is feeling anxiety about the well-being of the baby, they should ask a trusted doctor or midwife about coping strategies and discuss any fears and risk factors.

Q: Is it worth getting a Doppler Ultrasound?

A: Although ultrasounds are non-invasive and very low-risk, and there has been no evidence of harm from using fetal Doppler devices (which sends sound waves through your skin to confirm fetal sound or movement), the at-home variety hasn't been shown to provide any medical benefit.

Q: Can I eat before use Doppler Ultrasound?

A: Wear something with short or loose sleeves and loose fitting trousers so that the trouser legs can be rolled up. You will also be asked to remove your socks/ tights/stockings and shoes. You may eat and drink normally before the Doppler test.

Q: What week is best for Doppler Ultrasound?

A: Most women now get an ultrasound before 12 weeks. A fetal Doppler test normally takes place during your second trimester (weeks 13 to 28 of pregnancy). Some manufacturers of at-home fetal Dopplers say you may be able to hear your baby's heartbeat as early as 8-12 weeks of pregnancy.

Q: How do you clean a Doppler Ultrasound?

A: AFTER USE, the probe should be gently wiped clean of the Aquasonic or other acoustical coupling gel with a soft tissue. If gel has dried on the probe, place it under warm tap water (not hot) to soften the gel and permit you to wipe it off.

Q: How does a Doppler Ultrasound work?

A: Doppler ultrasound is a noninvasive test that can be used to measure the blood flow through your blood vessels. It works by bouncing high-frequency sound waves off red blood cells that are circulating in the bloodstream. A regular ultrasound uses sound waves to produce images, but can't show blood flow.

Q: Is the Doppler ultrasound safe?

A: It's generally considered safe when trained sonographers use it correctly. Doppler ultrasound doesn't use ionizing radiation like x-rays use, which makes it safer than x-ray. That's why ultrasound is the most widely used medical imaging method for viewing an unborn baby during pregnancy.

Q: Can Doppler ultrasound detect blocked arteries?

A: Doppler ultrasound testing allows doctors to clearly see how blood flows through the heart and blood vessels. It also lets them see and measure obstructions in arteries and measure the degree of narrowing or leakage of heart valves. It may be recommended for patients with atherosclerosis or coronary artery disease.

Q: Can Doppler detect stroke?

A: The carotid doppler test can help doctors determine stroke risk and the need for preventive measures. A carotid doppler test may be performed if you are considered to be at risk of having a stroke due to decreased blood flow in the carotid arteries.

Q: How do you read a Doppler Ultrasound at home?

A: Place a small amount of gel (Doppler gel only) on the probe at the end of the monitor. Then put the probe on your lower abdomen, near your pubic bone. Angle or tilt the probe, keeping contact between your skin and the probe at all times, until you hear a galloping sound — the fetal heart rate.
