Doppler Scan
A Doppler scan is a special type of ultrasound test used to evaluate blood flow through blood vessels and assess circulation in different parts of the body.
What is a Doppler Scan
A Doppler scan is a non-invasive imaging technique that uses high-frequency sound waves to measure the movement of blood through arteries and veins. Unlike a regular ultrasound that shows only structures, Doppler ultrasound can detect the speed and direction of blood flow.
The sound waves bounce off moving blood cells and return signals that are processed to create visual images and color patterns on a screen. This helps doctors identify problems related to blood circulation without the use of radiation or injections.
What is a Doppler Scan Used For?
Evaluating blood flow in arteries and veins
Detecting blood clots or blockages
Assessing varicose veins and venous insufficiency
Monitoring blood flow during pregnancy
Checking blood supply to organs and tissues
Diagnosing conditions like deep vein thrombosis (DVT) and peripheral artery disease
Our Doppler Scan Process
A Doppler scan involves assessing blood flow using ultrasound technology. The process generally includes:
Preparation
The patient is asked to lie comfortably, and a water-based gel is applied to the area being examined.
Scanning
A transducer is moved over the skin, sending sound waves into the blood vessels to capture blood flow information.
Signal Processing
The returning signals are converted into color images or waveforms that show the speed and direction of blood flow.
Result Review
The images and data are reviewed by a doctor or radiologist to identify any abnormalities in circulation.
