MRI techniques like phase-resolved functional lung imaging (PREFUL) offer the possibility for pulmonary ventilation (V) / perfusion (Q) imaging without ionizing radiation or contrast agents. One major drawback of such methods is the long acquisition time, if a whole lung coverage is required. In this study, five healthy volunteers were scanned with a highly accelerated 2D multi-slice real-time PREFUL (RT-PREFUL) acquisition with compressed sensing and parallel imaging reconstruction to establish a V/Q scan of the whole lung in one minute. The comparison with conventional PREFUL technique showed very similar ventilation results and comparable perfusion results with 9-fold acceleration.
