Arterial spin labeling (ASL) is having many applications outside the brain. In the abdomen, many problems arise with the traditional single shot EPI acquisition for ASL such as distortion, low spatial resolution, susceptibility artifact, Nyquist ghost, and chemical shift. A turbo field echo (TFE) acquisition with STAR labeling (STAR-TFE) was developed to overcome these problems and applied for abdominal ASL at 3T. Significant image quality improvement was achieved. STAR-TFE has comparable temporal resolution with HASTE and b-ssfp acquisition, but with lower SAR and no banding artifact. STAR-TFE should be promising for abdominal perfusion in spinal bone marrow and kidney.
