【摘 要】目的：探讨多层螺旋CT(MSCT)对急性阑尾炎的诊断价值。方法：收集临床疑诊和经手术和病理证实为急性阑尾炎患者35例，回顾分析其CT表现。结果：26例确诊急性阑尾炎病例中主要CT征象有：阑尾肿大24例(92%)，阑尾粪石10例(38%)，回盲部肥厚12例(46%)，阑尾周围炎20例(77%)，局限性脓肿2例(8%)。对照手术病理，MSCT诊断急性阑尾炎准确率89%、敏感性92%、特异度74%、阳性预测值92%、阴性预测值71%。结论：MSCT显著提高了急性阑尾炎的术前诊断能力，应成为临床首选的影像学检查方法。

    【Abstract】Objective：To evaluate the value of multi-slice spiral CT for acute appendicitis.Methods：Thirty-five cases acute appendicitis suspected or confirmed by pathology were retrospectively analyzed. Results：CT findings of 26 acute appendicitis included englarged appendix (92%), appendical calculus (38%),caecalapical thickening(46%), periappendicitis (77%),and abscess(8%). The MSCT imaging compared with the surgical and pathologic findings ......
