双源双能量CT心肌灌注成像在冠状动脉以及心肌灌注联合诊断中的应用价值

The Application Value of Myocardial Perfusion Imaging of Dual energy CT in the Diagnosis of Coronary artery and Myocardial Perfusion in Combination

目的探讨双源双能量CT心肌灌注成像在冠状动脉以及心肌灌注联合诊断中的价值。方法选取2013年1月至2014年12月收治的接受双源双能量CT检查的28例冠状动脉疾病患者作为研究对象,采用双源双能量CT检查其冠状动脉以及心肌灌注情况。结果 28例冠状动脉疾病患者中,15例患者的31支冠状动脉分支有狭窄或闭塞等表现,其中轻度狭窄19支,中度狭窄5支,重度狭窄5支,闭塞2支;476个左室心肌节段中,左心室心肌灌注评分为2分居多,占42.9%(204/476),其次为3分,占38.4%(183/476)。结论双源双能量CT心肌灌注成像作为一站式检查手段,在冠状动脉以及心肌灌注联合诊断中存在明显优势,临床价值较高。

Objective To investigate the myocardial perfusion imaging of dual energy CT in the diagnosis of coronary artery and myocardial perfusion in value.Methods Select 2013 January 2014 to 12 months in our hospital from accept dual energy CT examination of 28 cases of subjects were as the research object,the dual energy CT examination of the coronary artery and myocardial perfusion situation.Results In 28 subjects, 15 patients with 31 coronary artery stenosis or occlusion,including mild stenosis 5,moderate stenosis 19,severe stenosis 5,occlusion 2;476 left ventricular myocardial segment,left ventricular myocardial perfusion score was 2 points,3（204/476）, followed by 38.4%（183/476）.Conclusion Dual energy CT myocardial perfusion imaging as a one-stop examination means,in the coronary artery and myocardial perfusion combined with diagnosis exists obvious advantages,higher clinical value
