Comparative diagnostic yield and 3-month outcomes of "triple rule-out" and standard protocol coronary CT angiography in the evaluation of acute chest pain.

Background: "Triple rule-out" CT angiography simultaneously evaluates coronary artery disease, pulmonary embolism, and aortic dissection in a single imaging examination. However, the clinical outcomes of this approach are unknown.

Objective: Using standard cardiac CT angiography as a reference, this study was performed to describe the diagnostic yield and clinical outcomes of patients undergoing triple rule-out in clinical practice.
