Ancillary Findings on CT Pulmonary Angiograms that are Negative for Pulmonary Embolism.

Context: One advantage of computed tomographic pulmonary angiograms (CTPA) is that they often show pathology in patients in whom pulmonary embolism (PE) has been excluded. In this investigation, we identified the ancillary findings on CTPAs that were negative for PE to obtain an impression of the type of findings shown.

Methods: This was a retrospective analysis of findings on CTPAs that were negative for PE obtained in nine emergency departments between January 2016 - February 2018.
