1 Intermediate probability V/Q scan
Intermediate probability V/Q scan. (A) Ventilation images demonstrate no focal defects. (B) Perfusion images demonstrate a segmental defect involving the anterior basal segment of the right lower lobe (white arrows), giving an intermediate probability for pulmonary embolism. CT angiogram performed 5 days later did not demonstrate any pulmonary emboli, although the patient received anticoagulation in the interim, and it is conceivable that any potential thrombus may have resolved.
