Other methods, such as the ratio of the PSV in the aorta to the PSV in the renal artery (RAR) or indirect criteria, such as side to side differences in RI (dRI) or AT can be additionally used to improve accuracy. Contrast-enhanced ultrasound improves accuracy by means of echo contrast ...
Renal artery stenosis (RAS) is a common cause of hypertension and renal insufficiency, especially in the elderly population. There are several excellent diagnostic tests available to diagnose RAS. Renal artery duplex ultrasound, magnetic resonance angiography (MRA), and spiral CT angiography have been...
medications that block the actions of angiotensin [for example, captopril (Capoten), enalapril (Vasotec), losartan (Cozaar)] may be used in association with routine monitoring of the renal artery status with ultrasound.
Renal Artery Diagnosis The symptoms and medical history may raise the suspicion about renal artery stenosis. However, further diagnostic investigations are necessary to confirm the diagnosis. Blood and urine tests will indicate kidney dysfunction by an increase in the level of creatinine in the blood ...
Upon reaching the renal hilum, the main renal arteries divide into anterior and posterior segmental arteries. These further divide to feed the multiple segments of the kidney. The segmental arteries, in turn, give rise to the interlobar arteries which course alongside the renal pyramids toward the...

In this review we consider in detail the use of the following tests for the diagnosis of renal artery stenosis; intravenous urography, B Mode ultrasound, Doppler ultrasound, renal scintigraphy with angiotensin-converting enzyme inhibitors, intra-venous and intra-arterial catheter angiography, computed ...
