In the United States alone, nearly 6 million patients present annually to emergency departments with complaints of chest pain suspicious for acute coronary ischemia. Acute chest pain represents a clinical as well as economic challenge, often resulting in elaborate, time-consuming, and expensive evaluation to avoid litigation related to missed diagnosis of acute coronary syndromes (ACS). Coronary CT angiography (CCTA) is a rapid, widely available technique with promising initial results for use in the emergency department in patients with acute chest pain. Due to its high accuracy and sensitivity, CCTA can aid in safe, rapid, and cost-efficient triage of these patients. Latest-generation scanners and novel acquisition strategies demonstrate significant radiation dose reduction. Additional applications of plaque characterization and perfusion imaging hold promise in providing incremental data in patients with suspected ACS.
