Patients with renal transplants were images with two non-enhanced MRA techniques: quiescent-interval single-shot (QISS) and steady-state free precession (SSFP) with inversion recovery. Image quality and diagnostic findings were recorded by two observers. There were no significant differences in terms of image quality between the methods. Both observers had one misdiagnosis each using the SSFP MRA as gold standard. QISS is a potential alternative for the imaging of patients with renal transplants when there is insufficient blood flow.
