Pseudo-continuous-arterial-spin-labeling (PCASL) has been successfully applied in the liver and kidney providing high signal-to-noise-ratio. The goal of this work is to assess the potential of PCASL technique to measure the pulmonary perfusion at 1.5 T. Effective labeling of pulmonary blood flow was achieved by ECG triggering and an orientation of the labeling plane perpendicular to the pulmonary trunk. Fast True-FISP imaging with short TE of 0.9 ms was used to obtain high signal from lung parenchyma. The PCASL-True-FISP technique provides high quality perfusion images of the lung and allows quantitative measurements of pulmonary perfusion both in multiple breath-holds and under free breathing condition.
