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.

Emergency overreads change care for 92% of patients with discrepant outside reports

When emergency radiologists overread interpretations of critically ill transfer patients, they discover discrepancies in fewer than 15% of cases. However, more than 90% of these second opinions produce a change in patient care or follow-up.

Faster CT translates to fewer sedated children

Upgrading to dual-source, dual-energy CT machines cut average pediatric scan times from around 12 seconds to three seconds or less at two sites of an academic emergency department.
