摘　　要：目的：研究基于单次对比增强双源 CT 双能量成像的可行性。方法统计分析本院收治的60例接受双能量 CT 心脏检查患者的临床资料。结果60例患者共600段冠状动脉,所有阶段的图像质量均100%显示成功。图像质量评分总均值是4.68±0.57,达到了95%的图像优良率。接受 DSA 检查的6例患者 DECT 和 DSA 检查结果一致；接受 SPECT 检查的6例患者60个节段均没有灌注异常；DECT 碘图正常54个节段,灌注缺损6个节段。结论单次对比增强双源 CT 双能量成像在具有合适心率的情况下能够获得优良的冠状动脉及心肌灌注影像,具有一定的临床应用潜力。Objective To study the feasibility of dual-source CT with dual-energy imaging based on single contrast enhancement. Methods The clinical data of 60 cases of patients who underwent dual-energy CT （DECT）examination of the heart in our hospital were analyzed.statistically.Results The success rate of 60 cases were 100% for displaying all 600 coronary artery segments at all stages.The total mean score of image quality was 4.68 ±0.57,and the good image rate reached 95%.6 cases of patients who ac-cepted DSA examination were unanimous with DECT findings;In 6 cases of patients who accepted SPECT examination,60 segments were no perfusion abnormalities,but DECT iodine figures of 54 segments were normal,and 6 segments showed perfusion defect. Conclusion DECT with dual-energy imaging based on single contrast enhancement can get excellent coronary and myocardial perfu-sion imaging in the circumstance of appropriate heart rate,which has some potentials for clinical application.
