Renal Artery Doppler
Description - The renal artery ultrasound is a test the demonstrates the renal arteries, the arteries carrying blood to the kidneys. These areteries may narrow or become blocked resulting in kidney failure or high blood pressure (hypertension). Ultrasound waves are used to image the arteries and measure velocities and flow patterns to determine the degree of vessel narrowing,
Indications: Referring physicians will request a renal artery ultrasound for patients exhibiting signs of kidney failure or experiencing difficulty controlling blood pressure dispite multiple medications. Renal artery stenosis is the most common, correctable cause of hypertension. Long term, untreated renal artery disease can lead to kidney failure.
Procedure - The room is usually darkened for the exam. You will be asked to lie on a table and the technologist will place a clear gel onyour abdomen to provide good contact for the handheld transducer. The transducer sends sound waves into the body and is reflected off the structures of interest and returned to the transducer to produce images that can be viewed on a monitor. Scanning on the sides of the abdomen may also be required. All images are evaluated by a radiologist and a report sent to your referring provider. This procedure takes approximately 60 minutes.
Preparation - Nothing to eat or drink after midnight the evening before the exam.
