25 patients were enrolled in this study to evaluate the renal anatomy and renal stenosis in three-dimensional (3D) non-contrast enhanced MR angiography with a time-spatial labeling inversion pulse (Time-SLIP) compared with computer tomography angiography ( CTA). All subjects received both coronal and axial views of MRA with a Time-SLIP. The variants of renal artery were same and the evaluation of renal artery stenosis were consistent of the two image modalities. The discrepancy between them may related to the calcification of the renal artery and the change of the hemodynamic of the stenosis.
