目的探讨MSCT及MPR在宫颈癌诊断中的价值。方法回顾性分析125例宫颈癌患者的CT、临床、病理资料。全部患者均接受轴位平扫及增强扫描,并行冠状位及矢状位MPR。以FIGO及病理分期为对照比较CT轴位及MPR对宫颈癌术前分期的准确率。结果手术病理分期结果:原位癌3例,Ⅰa期41例,Ⅰb期36例,Ⅱa期34例,Ⅱb期6例,Ⅲa期2例,Ⅲb期1例,Ⅳ期2例。CT轴位扫描分期结果:原位癌及Ⅰa期0例,Ⅰb期9例,Ⅱa期12例,Ⅱb期4例,Ⅲ期3例,Ⅳ期2例。MPR对7例CT轴位未明确分期的Ⅰa期～Ⅱa期患者进行了准确分期。MPR图像与轴位扫描对Ⅰa～Ⅱa期的诊断准确率差异有统计学意义。结论 CT轴位扫描对早期宫颈癌的诊断准确率较低。MPR图像可以明显提高Ⅰa～Ⅱa期的诊断准确率,对判断Ⅱb期～Ⅳ期宫颈癌宫旁浸润、阴道受侵及远处转移有一定价值。
Objective To investigate the value of MSCT and MPR in the diagnosis of cervical cancer. Methods Retrospective analysis of 125 cases of cervical cancer patients CT, clinical and pathological data. All patients underwent axial plain and enhanced scanning, parallel coronal and sagittal MPR. The accuracy of preoperative staging of cervical cancer by CT and MPR was compared with FIGO and pathological staging. Results The pathological staging results of the surgery included 3 cases of carcinoma in situ, 41 cases of stage Ⅰa, 36 cases of stage Ⅰb, 34 cases of stage Ⅱa, 6 cases of stage Ⅱb, 2 cases of stage Ⅲa, 1 stage of stage Ⅲb and 2 stage of stage Ⅳ. CT axial scanning staging results: 0 cases of carcinoma in situ and Ⅰ a, Ⅰ b 9 cases, Ⅱ a 12 cases, Ⅱ b 4 cases, Ⅲ 3 cases, Ⅳ 2 cases. MPR accurately staged seven cases of stage Ⅰa ~ Ⅱa patients with undetermined staging of CT. There was significant difference between the accuracy of diagnosis of Ⅰa ~ Ⅱa in MPR images and axial scanning. Conclusion The accuracy of CT axial scan in the diagnosis of early cervical cancer is low. MPR images can significantly improve the diagnostic accuracy of Ⅰa ~ Ⅱa period, to determine Ⅱb ~ Ⅳ cervical uterine infiltration, vaginal invasion and distant metastasis of some value.
