Magnetic resonance angiography for the primary diagnosis of pulmonary embolism: A review from the international workshop for pulmonary functional imaging

Figure 1 Direct findings of pulmonary embolism. A: CE-MRA shows a filling defect in the interlobar artery (white arrow) consistent with the expected appearance of a pulmonary embolus (arrow); B: CE-MRA showing an eccentrically located pulmonary embolus that spans the truncus anterior and interlobar artery (arrow); C: Post gadolinium fat saturated breath hold axial spoiled gradient echo image showing bilateral filling defects in the lower lobe pulmonary arteries (interlobar PE-dashed arrow, left lower lobe pulmonary artery-arrow). CE-MRA: Contrast enhanced magnetic resonance angiograph; PE: Pulmonary embolism.
