Pulmonary CTA Reporting: AJR Expert Panel Narrative Review

Pulmonary CTA is a ubiquitous study interpreted by radiologists with different levels of experience in a variety of practice settings. Pulmonary embolism (PE) can range from an incidental and clinically insignificant finding to a clinically significant thrombus that can be managed on an outpatient basis to a potentially fatal condition requiring immediate medical or invasive management. Accordingly, a clear and concise pulmonary CTA report should effectively communicate the most pertinent findings to help the treating medical team diagnose or exclude PE and provide information to guide appropriate management. In this Expert Panel Narrative Review, we discuss the purpose of the radiology report for pulmonary CTA, the optimal report format, and the relevant findings that need to be addressed and their clinical significance.
