摘　　要：目的探讨老年人64层螺旋CT冠状动脉成像的技术特点及临床应用价值。方法对257例老年冠状动脉疾病患者行64层螺旋CT冠状动脉造影检查,针对老年患者的特点选用适合的检查技术,并评价所获得的图像质量;将患者按照年龄分组,分为65～74岁、75～84岁、≥85岁三组,分别统计各组CT冠状动脉成像的成功率并总结成像技术特点。结果 257例老年患者的2150段冠脉血管中,2041段冠状动脉血管(94.93%)图像质量可以满足影像学诊断。经统计学方法处理,表明在不同年龄组的老年患者中,冠状动脉成像显示成功率无显著性差异。结论 64层螺旋CT对老年人冠状动脉成像有很好的显示成功率,可作为老年人冠状动脉病变的一种有效筛选方法;在对老年人行CT冠状动脉成像检查时,根据老年人的特点适当的运用成像技术会获得良好的效果。Objective To investigate the techniques and evaluate the clinical application of 64-slice CT coronary angiogra- phy in aged people. Methods 257 patients with coronary artery disease （CAD） were enrolled in this study, and the CT image quality was graded as follows：A, excellent; B, good; C, poor; D, very poor. The image quality of A and B were sufficient in diagnosis. Estimate the imaging effect in different age groups （group A.. 65 to 74 years old; group B.. 75 to 84 years old; group C： over 85 years old） and summarize the point of techniques. Estimate the value of the 64-slice CT coro nary angiography in the diagnosis of the coronary disease. Results 94.93% of the coronary segments were sufficient for diagnosis in the 257 patients. The rate of success for coronary imaging was not related with age in statistics. Conclusion Coronary imaging with 64-slice CT showed a high sufficiency for diagnosis in aged people. According the features of aged people, using the appropriate techniques can be helpful for coronary imaging.
