What are Doppler ultrasound studies primarily used to assess?

Doppler ultrasound studies are primarily employed to assess blood flow and vascular conditions. This technique utilizes the Doppler effect to measure changes in frequency of sound waves as they bounce off moving objects, such as red blood cells. By analyzing these frequency changes, Doppler ultrasound can provide valuable information regarding the speed and direction of blood flow within vessels, enabling healthcare providers to evaluate the patency of blood vessels, identify areas of stenosis or occlusion, and assess various vascular conditions like deep vein thrombosis or cardiac output.

Using Doppler ultrasound is crucial in diagnosing and managing diseases related to the circulatory system, making it an essential tool in the field of diagnostic medical sonography.
