摘　　要：目的比较多排螺旋CT与超声在诊断不典型症状急性阑尾炎中的价值。方法对60例临床症状不典型,曾同时行多排螺旋CT与超声检查,最终临床拟诊为急性阑尾炎的患者进行回顾性分析,根据术后病理结果,分析两种检查方法的敏感度及特异度。结果多排螺旋CT与超声检查的敏感度分别为92.5%(37/40)、65.0%(26/40),特异度分别为85.0%(17/20)、55.0%(11/20),其敏感度及特异度差异均有统计学意义(P<0.05或0.01)。结论多排螺旋CT较超声在诊断不典型急性阑尾炎中更具有优势,在症状不典型但怀疑为急性阑尾炎病例中,超声检查阴性,可考虑CT进一步检查。Objective To compare the clinical value of multi-slice spiral CT（MSCT）and ultrasound in the diagnosis of atypical acute appendicitis. Methods Retrospective analysis was given to 60 cases with atypical symptoms, who were diagnosed with acute appendicitis after being examined by MSCT and ultrasound at the same time.The sensitivity and specificity of above-mentioned examination methods were analysed according to the postoperative pathological re- sults.Results The Sensitivity of MSCT was 92.5%（37/40） and that of ultrasound was 65.0%（26/40）.Their speci-ficity were 85.0% （17/20） and 55.0% （11/20）, respectively.Thus, their differences in both sensitivity and specificity were statistically significant（ P 〈0.05 or 0.01）.Conclusion MSCT has more advantages than ultrrasound in the diag-nosis of atypical acute appendicitis.If a patient with atypical symptoms and suspected acute appendicitis indicates nega-tive in the examination of ultrasound, MSCT can be used to give further examination.
