摘　　要：目的探讨MSCT增强多平面重组(multi-planar reformation,MPR)对原发性卵巢癌分期诊断价值。方法收集经手术病理证实的I^III期原发性卵巢癌患者70例,与术后病理分期比较,评价CT增强及MPR对原发性卵巢癌术前分期的准确性。结果手术病理I期11例,II期13例,III期46例,MSCT I期9例,II期10例,III期43例;CT分期准确率为88.57%;I、II、III期诊断的准确率分别为95.71%、88.57%、92.86%;敏感度为81.82%、76.92%、93.48%;特异度为98.31%、91.23%、91.67%;CT分期与术后病理具有极好的一致性,κ=0.778,P<0.05;对肿瘤直接浸润、腹盆腔种植转移、淋巴结转移、腹水等诊断准确性为85.71%~100%。结论MSCT增强MPR对原发性卵巢癌术前诊断及分期准确率高,可广泛应用于临床。Objective To investigate the value of multi-slice CT(MSCT)enhanced multi-planar reformation(MPR)in the staging diagnosis of primary ovarian cancer.Methods 70 patients with stage I-III primary ovarian cancer confirmed by surgical pathology were collected and compared with postoperative pathological staging to evaluate the accuracy of CT enhancement and MPR for preoperative staging of primary ovarian cancer.Results There were 11 cases of surgical-pathologic stage I,13 cases of stage II,46 cases of stage III,with 9 cases of MSCT stage I,10 cases of stage II,and 43 cases of stage III.The accuracy of CT staging was 88.57%.The accuracy of diagnosis of stage I,II and III was 95.71%,88.57%and 92.86%respectively.The sensitivity was 81.82%,76.92%and 93.48%.The specificity was 98.31%,91.23%and 91.67%.CT staging showed excellent consistency with postoperative pathology(κ=0.778,P<0.05).The accuracy of diagnosis for direct tumor invasion,abdominal and pelvic cavity metastasis,lymph node metastasis,and ascites was 85.71%~100%.Conclusion MSCT enhanced MPR has high accuracy in the preoperative diagnosis and staging of primary ovarian cancer,which can be widely used in clinical practice.
