title: [Diagnostic imaging in renal vascular diseases: old and new ways. Role of nuclear medicine].
abstract: Using the nuclear medicine procedures it is possible to evaluate the renovascular hypertension via the captopril test. Decreased renal blood flow due to stenotic vessel may produce a variety of findings on the renogram using both OIH-I131 and DTPA-Tc99m. Delayed transit time and excretion also may be detected. In this situation the sensitivity and specificity of Nuclear Medicine for RAS detection is very low. Using Captopril test is possible to detect enhanced modification on the shape of renogram due to Angiotensin Converting enzyme inhibition.
