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.

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
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...
