Abstract
Cardiac-gated multidetector computed tomography (MDCT) is an emerging diagnostic imaging modality to non-invasively assess for coronary artery disease (CAD) through coronary artery calcium scoring (CACS) and CT coronary angiography. With ECG gating, detailed visualization of the pulmonary arteries and thoracic aorta are possible as well. This study attempts to determine the utility of MDCT in emergency department (ED) patients presenting with chest pain. We hypothesized that ECG-gating would improve imaging quality and increase the sensitivity of detecting and excluding clinically significant coronary stenosis, pulmonary embolism (PE) and aortic aneurysm in patients presenting to the ED with chest pain.
