Radiologist Approval for CTPA in the ED: A Single-Centre Pilot Study Did Not Demonstrate a Statistically Significant
1Emergency Department, Nepean Hospital, Kingswood, New South Wales, Australia.
Objective:
Overuse of CT Pulmonary Angiography (CTPA) remains a challenge in emergency medicine. Some institutions resort to radiologist vetting to reduce unnecessary imaging. This is a pilot study that aims to investigate the effect of radiology vetting on the CTPA yield.
Methods And Results:
This is a retrospective study comparing CTPA yields with and without radiology vetting. The results showed that there was no statistically significant difference in CTPA diagnostic yield, 11.4% (CI 9.2-14.0) versus 10.2% (CI 6.8-14.6), p = 0.60.
Conclusion:
This study showed that removing radiologist approval for CTPA did not appear to reduce diagnostic yield.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
