AB  - A new computer system was proposed to evaluate abnormal motion of the ventricular 
      wall in patients with myocardial infarction. Multi-slice ECG-gated cardiac X-ray 
      CT (MSECT), a new technique developed in our laboratory, was the source of the 
      original image. Using this system, we reconstructed three-dimensional images, 
      calculated % shortening values of the entire heart, and visualized abnormal wall 
      motion on the ventricular surface, displaying three-dimensionally. Our initial 
      study of five patients with myocardial infarction showed good correlation between 
      the findings using this system and conventional echocardiography and 
      cine-ventriculography. Since the development of the ECG-gated method, the 
      application of CT to the study of heart diseases has progressed rapidly. In 
      patients with myocardial infarction, ECG-gated cardiac CT is used to visualize 
      infarcted myocardium and to evaluate impaired cardiac function. However, such 
      analyses were limited to single slices, because a large dose of contrast medium 
      was required to distinguish the ventricular chamber from the myocardium. By 
      adopting multi-slice ECG-gated cardiac X-ray CT images as the data source and 
      using three-dimensional reconstruction technique, this system is useful for 
      evaluating abnormal wall motion.
