2D Flow Alternating Inversion Recovery (FAIR) has been applied to measure non-contrast pulmonary perfusion in research environments, but its lack of coverage limits its applicability for clinical perfusion evaluation, where whole-lung coverage is often necessary. In this study, we optimized the multi-slice FAIR technique, including background suppression for robust image quality and inflow saturation to minimize the blood volume contribution, to measure pulmonary perfusion across the whole-lung at 3T.
