Noncontrast renal 3D MRA using time-spatial labeling inversion pulse (Time-SLIP) with respiratory triggering (Time-SLIP renal MRA) is proven to be valuable for non-invasive assessment of renal arteries. However, to our knowledge, there are no studies demonstrating the reproducibility of Time-SLIP renal MRA. Thus, we examined the reproducibility of Time-SLIP renal MRA and the result showed acceptable inter-scan agreement between the original and repeated scans.
