Kawasaki's disease (KD) is a vasculitis that predominantly affects children and can lead to the development of coronary artery aneurysms. These aneurysms can subsequently thrombose and occlude, which may lead to chest pain and other signs and symptoms of acute coronary syndrome in young patients. Coronary CT angiography, including 3D visualization techniques, is a common modality used in the follow-up of KD patients. In this series of three patients, we present the typical coronary artery imaging findings that can appear in these patients, with an emphasis on the use of the novel 3D technique of cinematic rendering (CR). CR utilizes a different lighting model than other 3D methods and is able to produce highly-detailed, photorealistic images. The potential advantages of CR images in understanding the complex mediastinal vascular anatomy and the relationships of coronary artery aneurysms to other anatomic structures are emphasized.
