Types of Doppler Ultrasound Tests that You Should Know About

In modern-day prenatal tests, ultrasound plays an important role. It is a high-frequency sound wave that can be effective in tissue diagnoses. Among various ultrasound tests, the Doppler test has a significance of its own.

What is a Doppler Test?

A Doppler test is a much more simple process compared to invasive procedures like venography. It is widely used to detect abnormalities in blood flow and diagnose problems like thrombosis. In the Doppler test, the sound waves do not bounce back after hitting the surface. As a result, it can be useful in tracking moving objects.

More About the Four Kinds of Doppler Tests:

Different Doppler tests in Kolkata are available for diagnosing any prenatal issues. These may be non-invasive procedures, but their effectiveness cannot be challenged. One can get more information about these tests from this blog.

Colour Doppler Test: One can obtain images of blood vessels by standard ultrasound tests. This type of Doppler test converts the sounds into different colours. These are overlaid on the blood vessel image, which helps to determine the speed of the blood flow. It can be effective in detecting blood clots in the body of the mother and the foetus.

Duplex Doppler Test: It is a specialised Doppler test that can determine the direction and speed of blood flow in the limbs. A combination of standard ultrasound methods produces a clear picture of the blood vessels. It is sometimes considered an alternative method of venography and arteriography.

Continuous Wave Doppler: In this process, the ultrasound waves are frequently transmitted via the transducer. A doctor analyses the findings of these sound waves to determine any abnormality in blood flow. Generally, a portable machine is used to provide a quick estimate of the condition. The change in the pitch of the sound waves can provide important information about blood flow through the vessels.

Power Doppler Test: This test is performed by using the amplitude of the Doppler signal. It is effective in capturing the moving particles. Power Doppler test can be the most effective procedure for detection of lesser velocity compared to other tests. This can inform one about the blood flow rate through veins and arteries in solid organs.
To get professional assistance in a wide range of Doppler tests, one can contact the Institute of Fetal Medicine. They have experts who have years of experience in this field. For more details, one can visit their website.

Why Are Doppler Tests Important During Pregnancy?

Unlike the older times, modern medicine has made much progress in different fields. Especially in pregnancy and fetus related problems, the usage of different advanced tests and technologies can now give an almost clear picture of the unborn baby and its development. Moreover, the tests are totally safe and completely pain-free. Among such tests, the Doppler test in Kolkata is suggested by all doctors. It is highly effective in detecting the growth, blood flow levels, heartbeats and heart rate of the unborn baby. 

Fetal medicine experts generally prefer running this test on every pregnant woman within the 2nd and 3rd trimesters. Since they are safe without any side effects, these tests are an effective way to find abnormalities in the fetus. 

Why are Doppler tests effective?

For would-be moms who are afraid of needles, the Doppler test is a non-invasive process. This is generally done through transvaginal scanning. The Doppler test is important because of the following reasons.

  • It helps to detect blood clots and the possibility of ectopic pregnancy.

  • It scans the images of the fluids and detects the direction of the flow of fluid. 

  • It helps to detect the effective flow of blood through the umbilical cord to the veins and arteries of the fetus. 

  • It helps in the detection of damaged arteries and veins of the fetus.

  • It checks the heartbeats and the heart rates and tries to identify the abnormalities in the same. 

  • It also helps to assess the possibility of kidney malfunctions in the unborn child. 

What is the process of conducting a Doppler test?

This is an easy process and is quite similar to a normal ultrasound. Generally would be moms remain anxious about the pain part. However, Doppler tests are completely safe, and there’s no pain or risk involved in the same either for the mother or the baby. The Doppler test machine is connected with speakers, and with the application of gel on the area, the ultrasound is conducted. 

The doctor listens to the sound waves and makes the diagnosis accordingly. Sometimes the blood pressure of the mother is measured while the test is going on. It is either done through transvaginal scanning or lower abdomen scanning. The choice depends on the agreed opinions of the patient and the doctor.
