【摘要 】 目的 探讨CT和磁共振成像(MRI)在原发性卵巢癌分期中的价值和限度。方法 收集42例原发性卵巢癌患者的临床资料，对照手术和病理，获得CT、MRI、CT加MRI各自的准确性、敏感性、特异性(简称三特性)及术前分期。结果 CT和MRI对评价子宫受侵和子宫直肠窝病变均较满意(三特性均≥80% )。CT在判断单侧或双侧卵巢肿瘤和腹膜种植性病变方面优于MRI，主要是敏感性较高；MRI则在显示包膜受侵或破裂、侵犯除肠管以外的盆腔脏器、子宫直肠窝病变以及淋巴结转移方面优于CT，三特性多数较高。CT、MRI及CT加MRI的分期准确性分别为73.7%、68.4%及70.6%(P>0.05)。对于多数部位病变的诊断，两者均显示特异性较高而敏感性偏低。结论 CT和MRI是原发性卵巢癌术前分期有效的影像学方法。

【Abstract】 Objective Toinvestigate values and limitations of CT and MRI applied in staging of patients withprimary ovarian carcinoma (POC). Methods Forty two patients with POCproven by radical surgery, laparotomy, and postoperative pathology were studied. Incomparison to surgical and pathological findings, sensitivity, specificity, and accuracyof CT, MRI and CT plus MRI were calculated. Staging by the three imaging methods wasobtained according to FIGO′s classification. Results CT and MRIshowed higher accuracy in evaluation of invasion to uterus (89.5% and 94.7%) and diseaseof Douglas pouch (94.7% and 97.4%). CT was to some extent superior to MRI in assessingipsilateral or bilateral tumor and lesions related to peritoneal seeding; MRI, however,had better capability of diagnosing invasion to ovarian capsule, pelvic organs excludingbowel, nodules in Douglas pouch, and metastasis to lymph nodes. The overall accuracy ofstaging by CT, MRI, and CT plus MRI was 73.7%, 68.4%, and 70.6%, respectively (P>0.05).Conclusion CT and MRI are useful imaging modalities in staging of POC,but low sensitivity for detecting involvement in some anatomic regions needs to beimproved.
