Doppler Ultrasound
Doppler ultrasound is an imaging technique that uses sound waves to measure and visualize blood flow through vessels and the heart by detecting frequency shifts from moving red blood cells. It helps diagnose clots, blockages, and circulatory abnormalities non-invasively.
What is Doppler ultrasound?
Doppler ultrasound is an imaging technique that uses sound waves to measure and visualize blood flow. It works by detecting the frequency shift that occurs when sound waves bounce off moving red blood cells, revealing the direction and speed of flow.
Because it is non-invasive and uses no ionizing radiation, it can be performed safely and repeatedly. It is commonly applied to vessels in the limbs and neck as well as to the heart.
Why is Doppler ultrasound useful?
By showing how blood moves through vessels, Doppler ultrasound helps clinicians detect clots, narrowing, and other circulatory abnormalities without surgery. This makes it a valuable first-line tool for evaluating vascular problems.
Its non-invasive nature and absence of radiation make it suitable for outpatient assessment, including evaluations relevant to surgical planning. Findings can influence whether and how a procedure proceeds.
