Colour Doppler Thyroid

A Doppler ultrasound is a radiological investigation which uses reflected sound waves to see how blood flows through a blood vessel. It helps clinicians evaluate blood flow through major arteries and veins, such as those of the arms, legs, and neck. During pregnancy, a Doppler ultrasound can be used to evaluate blood flow in an unborn baby to check the health of the fetus. It is a non invasive technique in which there is no risk of radiation exposure. It is totally safe during pregnancy.
