CT和MRI在卵巢癌定性、分期、侵袭和转移诊断中的价值以及临床应用

Invasion and metastasis, staging, qualitative diagnosis value and clinical application of CT and MRI in ovarian cancer

目的探讨卵巢癌的CT及MRI在诊断定性、分期及其对周围器官侵袭和转移的诊断价值及临床意义。方法对68例卵巢癌患者术前同时行CT和MRI检查,结合手术结果、病理诊断与临床分期对照分析。结果 (1)CT对卵巢癌的诊断符合率为80.9%(55/68),MRI为92.6%(63/68),MRI优于CT(χ2=3.0235,P<0.05)。(2)MRI对卵巢癌的定性诊断优于CT(χ2=4.2531,P<0.05),分期诊断优于CT(χ2=5.7129,P<0.05)。(3)MRI对转移至肠道、子宫及输卵管、肝脏等远处及淋巴结的诊断敏感度显著高于CT(P<0.05);对转移至腹膜、网膜的诊断敏感度略低于CT(P<0.05)。CT诊断卵巢癌转移的诊断总符合率为75.4%(46/61),MRI为88.5%(54/61),MRI显著高于CT(χ2=10.1723,P<0.05)。结论 MRI对于卵巢癌定性、分期及肿瘤侵犯周围器官和转移的诊断显著优于CT,二者联合应用,可以提高卵巢癌的诊断率。

Objective To investigate the invasion and metastasis, staging, qualitative diagnosis value and clinical application of CT and MRI in ovarian cancer. Methods CT and MRI were performed in68 patients with ovarian cancer before operation, then to have a comparative analysis compared with the operation results, pathologicaldiagnosis and clinical staging. Results （1）Diagnostic accordance rate of CT and MRI were 80.9%（55/68） and 92.6%（63/68） respectively.That of MRI was better than CT（χ2=3.0235,P〈0.05）. （2）MRI Characterization diagnosis on ovarian cancer was better than that of CT（χ2=4.2531, P〈0.05）, and stage at diagnosis was also superior to that of CT （χ2=5.7129, P〈0.05）. （3）MRI＇s diagnostic sensitivity of metastasis to the intestinal tract, uterus and fallopian tubes, such as the liver and lymph node was significantly higher than that in CT （P〈0.05）, but it was slightly lower than CT （P〈0.05） of metastasis to peritoneal, omental. Metastasis diagnosis coincidence rate of CT in ovarian cancer was 75.4%（46/61）, MRI was 88.5%（54/61）, MRI was significantly higher than that of CT （χ2=10.1723, P〈0.05）. Conclusions The MRI diagnosis on characterization, staging, qualitative tumors invading the peripheral organs MRI for ovarian cancer and metastasis of ovarian cancer was superior to that of CT. The combination of MRI with CT, can improve the rate of diagnosis of ovarian cancer.
