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.

New data highlight inconsistencies in imaging protocols for pediatric appendicitis

Utilization of MRI for cases of suspected appendicitis in the pediatric population is beneficial, yet its use varies across institutions.

Providers still routinely using unnecessary imaging to diagnose mild traumatic brain injury

There is little value in deploying CT, MRI or X-ray to diagnose mTBI, experts note, and it may instead result in harm and excess costs.
