Little attention is usually paid to the heart on non-electrocardiogram (ECG)-gated multi-detector computed tomography (MDCT) imaging of the thorax and abdomen. The current MDCT systems have fast scanning capabilities that render non-ECG-gated images with reduced cardiac motion artefacts due to greater temporal and spatial resolution. This has allowed for better evaluation of the cardiac structures. We present a pictorial review of incidental cardiac abnormalities found on MDCT imaging of the thorax and abdomen performed in our institution. We systematically describe abnormalities involving the pericardium, myocardium, cardiac valves, cardiac chambers, coronary artery and congenital heart disease. Some of these images have echocardiograph and magnetic resonance imaging correlation. The purpose of this pictorial essay is to draw attention to cardiac abnormalities found incidentally on non-ECG-gated MDCT imaging of the thorax and abdomen, which may or may not be related to the patient’s symptoms.
