Abstract
Pseudo-continuous-arterial-spin-labeling (pCASL) has been successfully applied in the brain and kidney providing high signal-to-noise-ratio. The aim of this study was to optimize pCASL for measurement of lung perfusion by optimized labeling of pulmonary arteries and fast signal acquisition. Effective labeling of pulmonary arteries was possible by ECG triggering and an appropriate orientation of the labeling plane. Sufficient signal from lung parenchyma was acquired by True-FISP imaging with TE=1ms. The presented method provides high quality perfusion images of the lung without applying intravenous contrast agents and offers diagnostic imaging of lung diseases such as pulmonary embolism and bronchial carcinoma.
