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.
