The multidetector CT scanner speeds diagnosis and treatment of patients. One of its many uses is to perform CT coronary angiography. Multidetector CT has generated excitement within the cardiology and radiology community as it provides clear pictures and takes less time than other non-invasive techniques, including conventional spiral and electron-beam CT which can take up to an hour or more. This atlas presents over 160 illustrations, with 116 in color and illustrates the capacity of multidetector CT for the analysis of the anatomy of the coronary arteries.
