      【摘要】 目的 探讨64层螺旋CT 100 kV低剂量平扫方法诊断急性阑尾炎的价值。方法 回顾性分析上海中医药大学附属第七人民医院2015年3月至2017年8月期收治的97例临床怀疑急性阑尾炎患者的临床病理及影像资料，按照就诊时间分成A组和B组，A组55例使用常规剂量CT扫描，B组42例使用低剂量CT扫描，对比2种扫描方法的图像质量、辐射剂量和影像术前诊断准确性。结果 A组与B组患者的影像图像质量均达到诊断要求，A组图像合格率为96.3%，B组图像合格率为97.6%，两组比较差异无统计学意义(P>0.05)；A组有效辐射剂量为(5.14±0.77)mSv，B组有效辐射剂量为(3.28±0.42) mSv，B组辐射剂量明显低于A组，差异具有显著统计学意义(P<0.01)；A组术前诊断准确性为90.9%，B组术前诊断准确性为90.5%。结论 64层螺旋CT 100 kV低剂量平扫方法能满足急性阑尾炎的临床诊断要求，辐射剂量低，值得推广使用。

【Abstract】 Objective To evaluate the value of 64-slice spiral CT with 100 kV low-dose plain scanning proto-cols in the diagnosis of acute appendicitis. Methods A retrospective analysis was conducted using clinical pathologicaldata and imaging data of 97 patients with clinically suspected acute appendicitis admitted to the Seventh People's Hospi-tal of Shanghai University of TCM during March 2015 and August 2017, who were divided into group A and group B ac-cording to the time of examination. Group A (n=55) received conventional dose CT scan, while group B (n=42) used·论 著·doi:10.3969/j.issn.1003-6350.2018.17.022
