【摘要】 目的：研究多层螺旋CT(MSCT)及多平面重建技术(MPR)在诊断急性阑尾炎中的临床价值。方法：回顾性分析本院2018年1月-2019年12月收治的疑似急性阑尾炎并手术的患者202例，采用MSCT横断面(对照组)及MSCT横断面+MPR(试验组)两种方法进行诊断，并将两种方法的诊断结果与手术病理进行比较。结果：试验组术前诊断发现阑尾炎189例，误诊4例，漏诊3例，对照组术前发现阑尾炎166例，误诊7例，漏诊29例;试验组的可信度(85.64%)明显高于对照组(59.41%)，差异有统计学意义(P<0.05);将试验组和对照组分别与手术病理进行Kappa一致性检验，发现试验组(Kappa=0.722)诊断结果优于对照组(Kappa=0.200)。结论：MSCT多平面重建提高了阑尾炎的诊断准确率，具有很强的优势。

    [Abstract] Objective： To explore the clinical value of multi-slice spiral CT (MSCT) and multiplanar reconstruction (MPR) in the diagnosis of acute appendicitis. Method： A retrospective analysis was performed on 202 patients admitted to our hospital from January 2018 to December 2019 for diagnosis of suspected acute appendicitis and surgery. The diagnosis was carried out by two methods： MSCT cross section (control group) and MSCT cross section+multi-plane reconstruction MPR (test group). The diagnostic results of the two methods were compared with surgical pathology. Result： In test group ......
