Diagnostic Accuracy of Computed Tomography Pulmonary Angiography With Reduced Radiation and Contrast Material Dose

Abstract

The accuracy of low-dose CTPA at 80 kVp with a 30% reduced radiation dose and a 25% lower CM volume is not significantly different from that of normal-dose CTPA at 100 kVp in detecting acute PE in patients weighing less than 100 kg.
