Doppler Renal Artey Stenosis Evaluation
Doppler renal artery stenosis evaluation is a non-invasive test used to evaluate blood flow in the renal arteries, which are the arteries that supply blood to the kidneys. The test is used to detect stenosis, or narrowing, of the renal arteries.
During the test, a special ultrasound machine called a Doppler ultrasound is used to evaluate the blood flow in the renal arteries. The Doppler ultrasound uses high-frequency sound waves to create images of the blood vessels and to measure the velocity of blood flow. By analyzing the velocity of blood flow in the renal arteries, doctors can determine if there is any narrowing or blockage in the arteries.
If Doppler renal artery stenosis evaluation suggests the presence of stenosis, further diagnostic tests such as angiography or CT angiography may be necessary to confirm the diagnosis and to plan for treatment.
