Fig. 1B. —45-year-old woman with acute pulmonary embolism. Source
images of time-resolved contrast-enhanced MR angiography using SENSE reveal
thrombi (arrows) in anterior truncus, right interlobar artery, left
pulmonary artery, left upper lobe trunk, and descending trunk on left, and
perfusion defect (small arrowheads) in left superior segment of lower
lobe. Reduced pulmonary blood flow (large arrowheads) in right middle
and lower lobes indicates high probability of pulmonary embolism in right
middle and lower lobe pulmonary arteries.
