Multicenter StudyPredictive value of perfusion defects on dual energy CTA in the absence of thromboembolic clots.
To determine the predictive value of volumetrically measured lung perfusion defects (PDvol) and right ventricular dysfunction on dual-energy computed tomography angiography (DE-CTA) for predicting all cause mortality in patients suspected of pulmonary embolism (PE) but without evident thromboembolic clot on CTA. ⋯ In the absence of thromboembolic clots, PDvol at DE-CTA appears to be predictive for all cause mortality.
