Pitfalls in Cardiac CT: Causes and Solutions

Abstract

Cardiac CT is used increasingly in the evaluation of cardiac abnormalities, particularly for coronary artery diseases. Cardiac CT mainly provides morphological information, but it also can generate some functional information. Cardiac CT can be performed either with prospective electrocardiogram (ECG) triggering or retrospective ECG gating. Several pitfalls can be seen in cardiac CT, and these can be confused for abnormal cardiac lesions. In this article, we provide solutions to avoid their misdiagnosis.
