摘要
目的分析在冠状动脉支架内腔再狭窄评估时,64层与128层螺旋冠脉CTA的价值差异。方法将50例2014年1月至2016年1月收治的冠状动脉金属支架植入术患者,分为64层螺旋冠脉CTA检查组及128层螺旋冠脉CTA组;以冠状动脉造影检测作为诊断金标准,比较两组扫描检查图像质量,比较两组诊断效能。结果128层螺旋冠脉CTA图像质量评分高于64层螺旋冠脉CTA扫描,且差异存统计学意义(P<0.05);128层螺旋冠脉CTA检查时共12例阳性、13例阴性,64层螺旋冠脉CTA检查时共21例阳性、4例阴性;128层螺旋冠脉CTA诊断特异度、阳性及阴性预测值和诊断准确率均显著高于64层螺旋冠脉CTA诊断,128层螺旋冠脉CTA检测的图像质量优于64层螺旋冠脉CTA图像。结论 128层螺旋冠脉CTA的诊断效能显著高于64层螺旋冠脉CTA。
Objective The value difference between 64 slice and 128 slice spiral coronary CTA in the evaluation of coronary stent restenosis was analyzed.Methods The coronary artery stenting in 50 patients from January 2014 to January 2016,divided into 64 slice coronary CTA examination group and 128 slice coronary CTA group;coronary angiography detection is the gold standard of diagnosis,compared with two groups of scan image quality,diagnostic efficacy between the two groups.Results 128 slice coronary CTA image quality score higher than 64 slice coronary CTA scan,and the difference is statistical significance(P<0.05).128 slice coronary CTA examination were positive in 12 cases,13 cases were negative,64 slice coronary CTA examination were positive in 21 cases,4 cases were negative;128 slice spiral CTA in the diagnosis of coronary artery.Specificity,positive and negative predictive value and diagnostic accuracy were significantly higher than that of diagnosis of 64 slice spiral CTA coronary artery,The image quality of the 128 slice spiral coronary CTA is better than that of the 64 slice spiral coronary CTA.Conclusion The diagnostic efficacy of 128 slice spiral coronary CTA is significantly higher than that of 64 slice spiral coronary CTA.
