CTVPA,is a “one-stop examination,” requiring only a few additional minutes—although the overall radiation dose is higher, there are more images to review, and the dose of IV contrast needs to be higher for optimal venous enhancement compared with CTPA alone. • ~ 30% lower dose than routine abdomen-pelvis scan is a good target. The purpose of these CT protocol pages is to provide a reference for radiology residents, fellows and technologists when prescribing a CT examination.
