The role of magnetic-resonance tomography and angiography in diagnosis of renovascular hypertension

Sensitivity, specificity and accuracy of magnetic resonance angiography, ca ptopril-sensitive dynamic scintigraphy, ultrasound dopplerography and combi nation of these techniques for detection of renovascular hypertension were assessed basing on examination of 67 patients with renal artery stenosis, 3 7 patients with hypertension and normal renal arteries and 22 healthy volun teers. Results allowed to create an algorithm for examination of patients w ith hypertension aimed at diagnosis of renovascular hypertension. Variants of magnetic resonance images of renal arteries with stenoses of different s everity and etiology were investigated. The technique of functional magneti c resonance tomography of the kidney was verified both on healthy subjects and patients with renovascular hypertension.
