• The clinical usefulness of MDCT (multidetector-row-CT) is determined by its ability to obtain thinner slices through a wider portion of the body. Thus, MDCT provides improvement of time resolution and high quality reconstruction images. In particular, clinical application for the heart and coronary arteries is difficult by CT, excluding EBCT (electron beam CT), because of its poor time resolution. However, MDCT has improved the time resolution of CT and is used for cardiac and coronary disease evaluation. Reports regarding delineation of cardiac diseases with MDCT have recently increased and many successful cases have been reported. We developed a cardiac phantom for ECG gated MDCT to better understand the function of MDCT. The phantom closely simulates motion of the left ventricle while providing a valuable tool to evaluate coronary stenosis and calcification making this newly developed cardiac phantom for ECG gated MDCT useful for functional evaluation of cardiac MDCT.
