title: Retrospective ECG-gated left ventriculography using multislice CT following left ventricular bolus injection and evaluation of its utility and motion artifact at every cardiac phase.
abstract: Following left ventricular bolus injection of contrast material, multislice CT scanning was performed. With retrospective ECG-gated reconstruction, we could acquire volume data for the heart at any cardiac phase and selectively depict only the left ventricle and aorta with maximum intensity projection. Temporal resolution of multislice CT was not sufficient to eliminate motion artifact except just before atrial contraction periods.
