Emergency Computed Tomography

Abstract

Emergency computed tomography (CT) is a diverse and growing area of advanced diagnostic imaging. Improved technology has led to increasingly rapid, specific, and sensitive examinations for indications for trauma and nontrauma emergencies. Emergency examinations constitute a large, complex, and changing use of CT. Although this article cannot address all indications for emergency CT or all emergency CT examinations, this overview of emergency CT discusses indications, the role and use of CT, and CT methods for emergency situations encountered by CT staff working in or serving emergency departments.
