摘要 目的探讨负荷动态心肌CT心肌灌注成像(CT-MPI)联合冠状动脉CT血管成像(CCTA)对冠心病(CHD)患者心肌缺血诊断效能的影响。方法选取2014年5月~2017年7月收治的128例疑似CHD患者作为研究对象,均接受CT-MPI、CCTA检查,并于1周内接受核素心肌灌注显像(SPECT-MPI)检查。统计CT-MPI、CCTA两者联合诊断的准确度、特异性、灵敏性。结果以SPECT-MPI为金标准。128例疑似CHD患者,确诊78例心肌缺血患者;CCTA确诊63例心肌缺血患者;CT-MPI确诊65例心肌缺血患者;两者联合确诊77例心肌缺血患者;两者联合诊断的灵敏性、准确性高于CCTA、CT-MPI单项诊断,差异有统计学意义(P <0.05);两者联合诊断特异性与CCTA、CT-MPI单项诊断比较,差异无统计学意义(P> 0.05)。结论 CCTA、CT-MPI联合可提高CHD患者心肌缺血诊断灵敏性及准确度,为临床准确评估心肌缺血情况提供指导信息。
