Multi-detector coronary CT angiography (CCTA) has emerged as the standard reference for evaluation of coronary artery anomalies. The clinical manifestations vary in severity. Although some are benign, others can cause severe symptoms, cardiovascular sequelae, or even sudden cardiac death. Therefore, it is important for the reader to be thoroughly familiar with the normal, abnormal, and anomalous findings on CCTA images.

Educational Goals / Teaching Points
We prepared a quiz-based review of rare, yet clinically significant, cases of the anomalous and abnormal coronary artery. The goals of this exhibit are as follows: 1. Incorporate a thorough familiarity of normal, abnormal and anomalous coronary artery findings, 2. Recognize the cross-sectional, 2D multi-planar reformation (MPR), 3D maximum-intensity-projection (MIP) and 3D volume-rendered image findings of abnormal and anomalous anatomy of the coronary arteries, and 3. Discuss the clinical manifestations and significance of each anomalous anatomy and abnormal condition.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Anomalies of the coronary arteries are uncommon but important. Some cases can lead to significant hemodynamic abnormalities and even sudden cardiac death. With increased availability of multi-detector CT (MDCT), temporal and spatial resolution of the coronary arteries has improved. Enabling the usage of 2D MPR, 3D MIP, and 3D volume-rendering techniques, the detection and characterization of coronary artery disease and delineation of coronary anatomy has become a routine. As of today, multi-detector coronary CT angiography (CCTA) has emerged as the standard for evaluating the coronary arteries.

Multi-detector CCTA has emerged as the standard reference tool for evaluating the coronary arteries. Familiarity of cross-sectional, 2D MPR, 3D MIP and 3D volume-rendered images and knowledge of such entities are essential for accurate diagnosis and proper patient treatment.
