【摘要】 目的 探讨利用电子束CT( EBCT) 心肌灌注色彩编码技术分析心肌缺血性改变的影
像学意义及临床价值。方法 34 例临床诊断心肌缺血患者进行了EBCT 长轴或短轴多层电影和血
流检查, 经后处理得到左室心肌色彩编码参量图像及相关参数。34 例中, 心电图诊断心肌缺血28 例,
超声心动图诊断心肌缺血31 例, 核素心肌显像检查报告34 例61 个节段心肌缺血。结果 EBCT 检
查报告34 例54 个节段心肌缺血, 前壁18 个节段、前间壁4 个节段、侧壁15 个节段、下后壁9 个节段、
心尖8 个节段。EBCT 报告心肌梗死的6 例, 核素心肌显像检查均得到同样的诊断。结论 心肌灌注
色彩编码参量图可客观反映心肌的缺血性改变, 与核素心肌显像检查有良好的一致相关性, 且直观效
果强; 同时, 能为EBCT 冠状动脉造影诊断冠状动脉狭窄提供佐证信息, 提高其诊断准确性。

【Abstra ct 】 Objective To analyze iconography significance and clinical value of ischemic change of
myocardium by using color code technology of MP with EBCT. Methods Thirty-four cases of patients with
myocardial ischemia ( MI) were performed multilayer image examination and blood flow examination by
EBCT, and parametric images of color code of myocardial and correlative indexes were got after be
processed. There were 28 cases of MI diagnosed by ECG, 31 cases by ultrasound cardiogram and 34 cases in
61 segments by myocardial image. Result s It showed according to EBCT that there were 34 cases of MP in
54 segments , 18 cases in antetheca, 15 cases in side wall and 8 cases in cordis apex. Besides , it showed
that there were 6 cases of myocardial infarction, and the same results were got by myocardial perfusion
imaging ( MPI) . Conclusion Parametric image of myocardial perfusion color code can objectively reflect the
ischemic change of myocardium, which had good correlation with MPI; meanwhile, it can give information to
coronary artery disease with coronary angiography by EBCT and improve the accuracy of diagnosis.
