【摘要】目的：分析穿孔性阑尾炎与非穿孔性阑尾炎的CT鉴别诊断价值。方法：本次研究开始时间定为2021年12月，结束时间定为2022年11月，选取该期间到我院接受诊疗的阑尾炎患者作为研究对象，总例数为86例，根据手术和病理检查结果的不同进行分组，将其分为穿孔组(n=43)、非穿孔组(n=43)，对所有患者均实施CT诊断，对其CT检查结果的差异性进行对比。结果：穿孔组患者的阑尾腔外粪石、阑尾腔外气体、阑尾周围脓肿、阑尾壁局限性强化破损、盆腔炎改变、阑尾周围炎(轻-重度)、阑尾周围炎(中-重度)等CT检查征象与非穿孔组相比存在明显差异(P<0.05)；穿孔组患者的阑尾腔外粪石、阑尾腔外气体、阑尾周围脓肿、阑尾壁局限性强化缺损特异性较高。结论：在判断穿孔性阑尾炎和非穿孔性阑尾炎的过程中，应用CT检查是一种有效的诊断方式，尤其是对于阑尾腔外粪石、阑尾腔外气体、阑尾周围脓肿、阑尾壁局限性强化破损等诊断时，其CT诊断具有明显的CT 征象，值得广泛应用。

    【Abstract】Objective：To analyze the value of CT in the differential diagnosis of perforated appendicitis and non-perforated appendicitis. Methods：The start time of this study was set to December 2021 and the end time was set to November 2022. A total of 86 patients with appendicitis who received diagnosis and treatment in our hospital during this period were selected as the research objects. They were divided into perforation group (n=43) and non-perforation group (n=43) according to different surgical and pathological examination results. CT diagnosis was performed in all patients ......
