Abstract
We present preliminary results of a prospective study of 96 patients examined with pCASL-MRI of the lung with suspected pulmonary embolism. pCASL-MRI of the lung was acquired in a 1.5T scanner by labeling the pulmonary trunk during systole. Coronal, sagittal and axial images were acquired using a fast bSSFP sequence. Additionally, a mulit-slice coronal bSSFP imaging the whole lung was performed. Two blinded readers evaluated MR-images to detect pulmonary embolism and noted the diagnostic confidence (5=very good). Compared to CT, sensitivity and specificity were 0.971 and 0.951. The median diagnostic confidence was 5 in both readers (kappa 0.739).
