In body perfusion measurement with arterial spin labeling technique, single shot acquisition was usually used, which suffers from susceptibility induced distortion. A straightforward way was to reduce readout echo train, which however lead to lower spatial resolution. In this work, we performed flow sensitive alternating inversion recovery (FAIR) with reduced FOV excitation to shorten echo train length while maintaining spatial resolution in prostate cancer perfusion imaging.
