About Color Doppler Ultrasound

Color Doppler Ultrasound is an advanced imaging technique used to evaluate blood flow through arteries and veins in the body. It combines traditional ultrasound imaging with Doppler effect technology, providing both structural and functional information about your circulatory system.

Why is it Done?

Doctors recommend a Color Doppler Ultrasound to diagnose and monitor conditions such as:

• Blood clots (Deep Vein Thrombosis)
• Narrowing or blockages in blood vessels
• Varicose veins
• Poor blood circulation in limbs
• Vascular tumors or malformations
• Pregnancy-related blood flow assessment in the umbilical cord and placenta

How the Test is Performed

During the test, a special handheld device (transducer) is placed over the area being examined. Sound waves bounce off moving blood cells, and the Doppler effect measures the changes in frequency, displaying them as color-coded images on a screen.

Benefits of Color Doppler Ultrasound

• Non-invasive and painless
• No radiation exposure
• Real-time visualization of blood flow
• Early detection of vascular problems

Preparation for the Test

• Wear loose, comfortable clothing
• Follow specific instructions from your doctor (e.g., fasting before abdominal scans)
• Stay hydrated unless told otherwise
