摘要
目的探讨急诊多层螺旋CT平扫对阑尾炎诊断的临床意义。方法收集急诊全腹CT平扫诊断为阑尾炎并经手术病理证实的25例病人CT资料(A组)和20例非阑尾炎病人的急诊全腹CT平扫资料(B组)进行回顾性分析。将两组资料混合,由两名(A医师、B医师)从事CT诊断工作10年以上,具有副高职称的医师在不知临床及手术结果的前提下分别盲法阅片,将两人的诊断结果以Kappa方式评价其一致性。以25例手术后阑尾炎病人为标准,分别计算两人诊断的敏感性、特异性及准确性。结果以A组病例为标准,A医师和B医师的诊断结果具有高度的一致性(Kappa值>0.75)。A医师的敏感性、特异性及准确性分别为92%、100%和95.5%;B医师的敏感性、特异性及准确性分别为88%、100%和93.3%。结论急诊多层螺旋CT平扫对阑尾炎的诊断具有很高的临床意义。
Objective To discuss the diagnostic clinical significance of appendicitis by multi-slice spiral CT （MSCT） plain scan during the emergency. Methods There were C＇F data of 25 patients （Group A） with appendicitis confirmed by surgery and pathology and CT data of 20 patients （Group B）which were non appendicitis patients. All pa- tients did MSCT plain scan. Group A and B were analyzed by associate chief physician A and B independently. Physician A and B didn＇t know clinical and surgical results and engaged in the CT image work more than ten years. Two people＇s diagnosis with kappa way to evaluate its consistency, in order to 25 cases of patient after surgery appendicitis as the standard, we calculated the two diagnostic sensitivity ,specificity and accuracy. Results A physician and B doctor diag- nosis results had a h were of 92%, 100% 93.3 %, respectively cance. gh degree of consistency （kappa value〉0.75）. A physician＇ s sensitivity , specificity and accuracy and 95.5%, respectively. B physician＇s sensitivity specificity and accuracy were of 88% ,100% and Conclusion Emergency MSCT plain scan to the diagnosis of appendicitis has high clinical significance.
