Temporal and spatial evaluation of pulmonary blood flow using multiple delay PCASL at 1.5 Tesla
{Pseudo-continuous-arterial-spin-labeling (PCASL) has been successfully applied in abdominal organs to image organ perfusion. The aim of this work was to evaluate the pulmonary blood flow in dependence on the cardiac cycle using PCASL at 1.5T. Labeling of pulmonary blood flow was achieved by ECG triggering and an labeling plane perpendicular to the pulmonary trunk (tagging duration 300ms). In five volunteers, eight measurements were acquired with fast True-FISP imaging (in-plane-resolution, 2.5$\times$2.5mm2, coronal view) with post-labeling delays between 100 and 1500ms. The PCASL-True-FISP technique was able to precisely assess blood flow of pulmonary arteries, as well as perfusion of the lung parenchyma.}
