We optimized non-enhanced 2D and 3D free-breathing black-blood imaging sequences and found excellent agreement in morphological measurements of renal artery (ICC: 0.85-0.95), and the CNR (p=0.17) and image quality score (p=0.60) were comparable between them. 2D imaging had higher SNR for lumen and wall visualization (all p<0.05) whereas 3D imaging had higher CNReff (5.37±1.91 vs. 0.87±0.51, p<0.01). Both sequences showed excellent inter-reader and scan-rescan repeatability (ICC: 0.77-0.99). We concluded that both 2D and 3D sequences are feasible for renal arterial wall imaging, particularly 2D provides high quality images whereas 3D sequence allows large-coverage and more efficient imaging.
