Although Arterial Spin Labeling (ASL) being a non-invasive detection method has been used for many years, the respiratory and cardiac motions present major challenges when applying ASL. In this study, to measure the renal blood flow (RBF), a new abdominal ASL method was proposed by using single-shot fast imaging employing steady-state acquisition (FIESTA) combined with flow-sensitive alternation inversion recovery (FAIR) perfusion preparation on clinical 3.0T MR scanner. Results showed that the proposed technique had the ability to satisfy the renal perfusion quantification requirements, and the low renal perfusion area was also revealed clearly in a patient with an angioleiomyolipoma.
