Doctors order this test to analyze if certain medical conditions are affecting the fetus. The color Doppler ultrasound utilizes sound waves to track the blood flow. This is safe because other scans use radiation, which is harmful for the fetus and may cause severe birth defects and other long-term repercussions.
There are two types of color Doppler:
Power Doppler is a more advanced variation that can generate images that are difficult to secure with the standard color Doppler. It is also more suitable for generating images of flow of blood within the vessels of solid organs.
Color Doppler ultrasound in pregnancy evaluates the flow of blood across different parts of the fetus’s body. Your doctor might recommend this if they suspect certain abnormalities in the fetus. Doctors may also recommend this when they suspect the fetus has a medical condition related to blood flow or placenta circulation.
These medical conditions include maternal conditions like: chronic hypertension and cardiac abnormalities. It also includes intrauterine growth restrictions.
No preparations are required for the test, unless your doctor advises any. Remember to wear loose-fitting clothes to help in undertaking the test. Also, remove all pieces of jewellery before you go for the color Doppler test as they act as a hindrance.
Your doctor may recommend repeating the test at regular intervals in case certain abnormalities were found during your first color Doppler ultrasound. Your doctor will measure the extent of abnormalities that are developing in the fetus. Pregnant women with a history of cardiovascular conditions and other medical conditions, may also need to repeat the color Doppler test at regular intervals. Previous history of complications during pregnancy may also be the reason for repeat tests.
Doctors use color Doppler ultrasound in pregnancy to monitor the blood flow of the fetus. Certain medical conditions may affect the blood flow. This procedure does not require preparation and is non-invasive.
