摘　　要：目的探讨64层螺旋CT曲面重建在急性阑尾炎诊断中的价值。资料与方法回顾性分析82例临床拟诊为急性阑尾炎而行64层螺旋CT检查和多平面重建(MPR)及曲面重建(CPR)的病例。其中,CT诊断急性阑尾炎61例,60例经手术病理证实为急性阑尾炎。结果 91.67%(55/60)成功获得曲面重建图像。应用64层螺旋CT曲面重建后,提高了阑尾系膜水肿、回盲肠壁水肿的显示率及阑尾识别率。64层螺旋CT结合多平面重建及曲面重建诊断急性阑尾炎的准确度为98.78%,灵敏度为100%,特异度为95.45%。阳性预测值为98.36%,阴性预测值为100%。结论 64层螺旋CT曲面重建可以准确地识别阑尾,从而做出急性阑尾炎诊断。Purpose To explore the diagnostic value of 64-slice spiral CT curved planar reconstruction （CPR） on acute appendicitis. Materials and Methods 82 cases with clinically suspected acute appendicitis underwent 64-slice spiral CT scanning. MPR and CPR were analyzed retrospectively. Sixty of 61 cases diagnosed as appendicitis by CT were confirmed by surgery and pathology. Results Satisfactory CPR images were obtained in 91.67% （55/60） of the cases.The discrimination rate of appendix and detection rate of appendix mesentery edema and ileocecum wall edema were improved. The accuracy was 98.78% with sensitivity 100%, specificity 95.45%, PPV 98.36%, and the NPV 100%. Conclusion 64-slice spiral CT CPR could accurately identify appendix and diagnose appendicitis.
