门电路心肌灌注断层显像能同时评价心肌灌注与心室室壁运动。它克服了因心脏搏动而引起的常规心肌断层显像中心室壁边缘不清的缺点，提高了图像分辨率和对ＣＡＤ的诊断灵敏度与分辨率，ＥＤ图像消除了局部容积效应的影响，反映心肌灌注缺损的范围和程度更加真实，舒张和收缩图像经计算机处理，可以提供反映心室室壁收缩厚度、心室室壁向心性运动和左心室腔射血功能等几种功能参数。评价心室室壁运动和心肌灌注、心肌组织的存活的关系，对临床心脏疾病的研究是十分有益的。
Gated myocardial perfusion imaging can simultaneously assess myocardial perfusion and ventricular wall motion. It overcomes the shortcomings of the edge of the ventricular wall of the conventional myocardial tomography center caused by heart beating, improves the image resolution and diagnostic sensitivity and resolution of CAD, ED images eliminate the effect of local volume effect, reflecting the myocardial The extent and extent of perfusion defects are more real. Diastolic and contractile images are computerized and provide several functional parameters that reflect the thickness of the ventricular wall, the ventricular wall-to-heart motion, and left ventricular ejection. Evaluation of ventricular wall motion and myocardial perfusion, the relationship between myocardial tissue survival, the study of clinical heart disease is very useful.
