Computed Tomography

Computed tomography (CT) is a fast and accurate imaging modality often used in emergency settings and trauma imaging. CT scans, with or without (or both) iodinated contrast are frequently used to image the brain, chest, abdomen and pelvis, but also have post-imaging reconstructive capabilities for detailed orthopedic imaging. It is now a standard imaging modality in emergency rooms to quickly assess patients. CT uses a series of X-ray images shot as the gantry rotates around the patient. Computer technology assembles these into into a dataset volume than can be slices on any access, or advanced visualization software can extract specific parts of the anatomy for study.

Lower shift volumes lead to significantly fewer errors for neuroradiologists

When case volumes climb to 67-90 studies, error rates were 226% higher than those tackling 19 or fewer cases during their shift, experts reported.

Use of CT angiography has surged in recent years, with a corresponding drop in MRI

Ease of access, lower cost, and shorter scan time, especially for emergent clinical indications such as acute stroke, all may be fueling CTA volumes.
