Less Common Causes of Disease Involving the Coronary Arteries: MDCT Findings

We aimed to illustrate and describe various imaging findings of nonatherosclerotic, nonanomalous coronary artery diseases (CADs) revealed by cardiac MDCT. Cardiac MDCT can show various causes of nonatherosclerotic CADs and of coronary atherosclerosis. Radiologists should be aware of the diverse imaging findings of nonatherosclerotic, nonanomalous CADs that can be identified with cardiac MDCT to facilitate accurate diagnosis and proper management.
