摘　　要：目的：探讨超声、MSCT多平面重建在临床表现不典型的急性阑尾炎诊断方面的价值。方法回顾性分析32例经手术病理证实的急性阑尾炎的患者资料，所有病例均行腹部超声检查及腹部MSCT增强检查。分别依据超声检查、MSCT多平面重建对是否是急性阑尾炎进行诊断，并对诊断信心评分（分3级）。结果MSCT多平面重建较超声检查可以提高急性阑尾炎的诊断正确率（93.8%vs 65.6%，P＜0.05）。超声及MSCT均诊断为阳性的病例，两种方法的诊断信心指数差异无统计学意义（P＞0.05）。结论超声检查可作为诊断临床表现不典型的急性阑尾炎的首选检查方法，MSCT多平面重建作为重要的补充检查方法有较高的临床价值。Objective To investigate the value of ultrasonography （US） and multiplanar reformation （MPR） with multi-slice computer tomography （MSCT） in the diagnosis of acute appendicitis （AA） with atypical clinical manifestation. Methods The image data of 32 patients with AA conifrmed by surgical pathology were retrospec-tively analyzed. All patients underwent US and enhanced MSCT scan in abdomen. Doctors diagnosed the presence of AA respectively on the basis of US and MSCT MPR. Diagnosis conifdence was scored with a 1～3 scale. Re-sults MSCT MPR can improve diagnostic accuracy of AA than US （93.8%vs 65.6%, P〈0.05）. The difference of the conifdence scores between MSCT MPR and US was not signiifcant on patients whose two examinations were positive. Conclusion US should be regarded as the ifrst imaging technique in patients for the diagnosis of AA with atypical clinical manifestation. MPR with MSCT, as an important complementary examination, has higher clinical value.
