[Myocardial imaging of patients with myocardial infarction--investigation of diastolic imaging by ECG-gated study].
ECG-gated thallium (201T1) myocardial diastolic imaging and non-gated imaging were performed in 22 patients with myocardial infarction. These patients were separated into 2 groups according to echocardiographic findings; Group A: the patients with left ventricular diastolic diameter of 5.5 cm and over and left ventricular ejection fraction of 50% and under; Group B: the others. In the patients of Group A, the low perfusion areas could be demonstrated qualitatively and quantitatively by nongated images as well as gated-diastolic images, while in some patients of Group B, low perfusion areas were shown only by gated-diastolic images, which seemed to be useful. The images gated in 100 ms after the peak of R wave in ECG were conformed as diastolic images by echocardiography, and could be obtained within a half or two thirds of the conventional imaging time.
