摘要
目的:比较64排CT冠脉成像(CTCA)与PET-CT心肌灌注显像(MPI)对相关冠状动脉狭窄,及准确定位"罪犯"血管的价值。方法:回顾性分析内蒙古医科大学附属医院2009年3月到2014年12月,在四周内进行CTCA与MPI的临床确诊及可疑的冠心病(CAD)患者59例,由2名有经验影像与核医学医师进行图像及数据分析,按照冠状动脉节段性供血特点,分析冠状动脉供血区域和心肌节段对应关系,采用Spearman等级相关、Pearson相关和Kappa检验方法。结果:59例患者按照LAD、LCX、RCA三支冠状动脉支配心肌部位来统计,合计177支血管,冠脉血管0级58支;Ⅰ级24支;Ⅱ级33支;Ⅲ级40支;Ⅳ级22支。灌注0分63支;1分30支;2分45支;3分27支;4分12支。三支冠状动脉CTCA与MPI分别行相关性分析和吻合度分析,两者为正性相关,吻合率较高。LAD r=0.764,P=0.000;LCX r=0.593,P=0.000;RCA r=0.831,P=0.000。LAD k=0.666,P=0.000;LCX k=0.601,P=0.000;RCA k=0.589,P=0.000。结论:CTCA的解剖学信息和MPI生理学功能性信息相互结合,有效互补,两者结合能够准确定位CAD患者的"罪犯"血管,大大提高CAD诊断准确率,为临床治疗及预后判断提供有力依据。
Objective： Comparison of CT coronary artery imaging（CTCA） and PET-CT myocardial perfusion imaging（MPI） for relevant coronary artery stenos is and pinpoints the value of the ＂criminal＂ blood vessels. Methods： A retrospective analysis of the Affiliated hospital of Inner Mongolia Medical University from March 2009 to December 2014,the clinical diagnosis and 59 patients with suspected CAD were used CTCA and MPI within four weeks. By two experienced imaging and nuclear medicine physician images and data analysis, according to the segmental coronary artery blood flow characteristics, analysis of coronary artery blood supply region and sarcomere corresponding relation we used the Spearman rank correlation and Pearson and Kappa test method. Results： According to the LAD, LCX, RCA three coronary artery myocardial part of dominion on 59 patients, total 177 vessels and coronary vascular level 0, 58 branch; 24 Ⅰ level; 33 the Ⅱ level; 40 Ⅲ level; 22 Ⅳ level. Perfusion 0, 63; 1 minute 30; 2 minutes and 45; 3 minutes and 27 teams; 4 points, 12.Three CTCA coronary arteries with MPI line of correlation analysis and alignment analysis respectively, both for the positive correlation, self-agreement is higher. LAD r = 0.764, P = 0.000; LCX r = 0.593, P = 0.000; RCA r = 0.831, P = 0.000. LAD k = 0.666, P = 0.000; LCX k = 0.601, P = 0.000; RCA k = 0.559, P = 0.000. Conclusion： CTCA anatomic information and MPI physiological functional combination, effective complementary, able to pinpoint a combination of CAD patients ＂criminals＂ blood vessels, greatly improve the CAD diagnosis accuracy, and provide powerful basis for clinical treatment and prognosis judgment.
