Zusammenfassung
Purpose: Magnetic resonance angiography (MRA) is gaining increased acceptance as a reliable test for the detection of renal artery stenosis (RAS). Purpose of this study was the evaluation of a high-resolution MRA of the kidneys at 3.0T in healthy volunteers and patients with suspected RAS. Methods: 15 healthy volunteers and 10 consecutive patients suspected of having RAS (17male, 8female, mean age 47.3 years) were scanned with a 3D-GRE Flash-sequence (TR/TE 2.9/1.2ms, flip 23°, matrix 576×432, voxel size 0.6×0.9×1.2mm3, GRAPPA 2, acquisition time 22s). Using an eight-channel phased-array surface coil on a 3.0T w…
