The development of newer generations of multidetector computed tomographic (CT) scanners capable of enabling accurate assessment of the coronary arteries in conjunction with the increasing placement of CT scanners near the emergency department has raised interest in using CT to provide a comprehensive imaging evaluation of patients presenting with acute chest pain. In this article, the authors review the challenges surrounding the current clinical and imaging work-up of chest pain in the emergency room and provide a framework for understanding the potential role of CT.
