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.

Dr. Saxena is Associate Professor of Radiology, St. John's Medical College Hospital, Bangalore, India; Dr. Rajiah is Associate Professor of Radiology and Associate Director, Cardiac CT and MRI, UT Southwestern Medical Center, 5323 Harry Hines Blvd, E6-122G, Mail Code 9316, Dallas, TX 75360, E-mail:; Dr. Quadri is Radiologist, and Dr. Saboo is Assistant Professor of Radiology, UT Southwestern Medical Center, Dallas, Texas.

After participating in this educational activity, the diagnostic radiologist should be better able to differentiate the various pitfalls encountered in cardiac CT, which can mimic cardiac lesions such as masses and thrombi, and to propose solutions to avoid these pitfalls.
