Zusammenfassung
Ziele: The purpose of this study was to assess interoberserver variability and accuracy in the evaluation of renal artery stenosis (RAS) with gadolinium-enhanced MR angiography (MRA) and digital subtraction angiography (DSA) in patients with hypertension. The authors find that source images are more accurate than maximum intensity projection (MIP) for depicting renal artery stenosis. Methode: Two independent radiologists reviewed MRA and DSA from 38 patients with hypertension. Studies were postprocessed to display images in MIP and source images. DSA, performed in each patient, was the standard for comparison. F…
