Tests to diagnose renovascular hypertension are gaining popularity as the treatment success improves. Angiotensin converting enzyme inhibition (ACEI) renography is the only imaging examination that tests directly for the presence of renovascular hypertension (RVH); other imaging examinations test for the presence of renal artery stenosis (RAS). The goal of ACEI renography is to detect those patients with hypertension who have RAS as the cause of their hypertension and who would benefit from revascularization. Consensus panels have recommended that ACEI renograms be interpreted as low, intermediate or high probability for RVH. ACEI renography is highly accurate in patients with suspected RVH who have normal or near normal renal function. In this patient population, the sensitivity and specificity of ACEI renography for renovascular hypertension exceed 90%. When azotemic patients present with suspected RVH, as many as 50% of patients may have an intermediate probability ACEI renogram and the sensitivity of detecting RVH falls.
This review summarizes general components of renal scintigraphy as well as those components specific to ACEI renography and semiquantitative diagnostic parameters.Keywords: Renovascular hypertension, renal scintigraphy, diagnostic approachesTurkiye Klinikleri J Int Med Sci 2005, 1(38):100-103
