Kinetics of Arterial Blood Transport in the Lung Assessed by PCASL True-FISP Imaging

摘要

The evaluation of the regional blood flow in pulmonary vessels and in lung parenchyma along the cardiac cycle can be of importance for the clinical diagnosis of lung diseases. Pulsed arterial spin labeling (ASL) techniques have been used for evaluation of the blood bolus delivery curve in the lung by a variation of the delay time between blood preparation and image recording.~1 However, acquiring only few number of label/control scans in a single breat hold, the sensitivity of this technique was not high enough to clearly reveal homogenous signal changes of the lung parenchyma.
