Pulmonary embolism is a common cardiovascular disease and thoracic CT angiography is currently considered the gold standard for its non-invasive diagnosis. However, the diagnostic performance of CT angiography can be hampered by an insufficient enhancement of pulmonary arteries. Contrast Enhancement Boost (CE Boost) is a post-processing technique using an iodine density map to artificially improve pulmonary artery enhancement. This retrospective study compares standard CT-angiography images with CE Boost images to assess the potential improvement of diagnostic performance for the detection of pulmonary embolism.

Contrast Enhancement Boost is a post-processing technique that uses an iodine density map generated by subtracting a pre- and post-contrast CT acquisition to artificially enhance pulmonary artery enhancement.

Number of thrombi within each branch of the pulmonary arteries
The pulmonary arteries were divided into 11 zones according to their anatomical characteristics then each visible thrombus was reported in a Excel table according to the zone where it was located
