Objective To evaluate the value of MRI imaging performance and preoperative staging of uterine cervical cancer. Methods Eighty-two patients with cervical cancer were examined by MRI. Lesion characteristics, including location, size, signal characteristics, infiltration range,adjacent involved uterine tissues and organs,and enlarged lymph nodes, were determined on MRI. Preoperative staging of cervical cancer was detected by the performance of MRI. Results Among the 82 patients, stage I cervical carcinoma was found in 32 (5 cases of stage I a and 27 cases of stage I b) , stage II cervical carcinoma in 38 (22 cases of stage II a and 16 cases of stage II b) , stage Ⅲ cervical carcinoma in 9 (6 cases of stage Ⅲ a and 3 cases of stage Ⅲb) ,and stage IV cervical carcinoma in 3 (2 cases of stage IVa and 1 case of stage IVb). Conclusion MRI can clearly show the infiltration of cervical lesions and whether tumor metastases occur. Therefore,MRI may be of great value in the staging and treatment options of cervical cancer.%目的 探讨子宫颈癌的MRI影像表现与术前分期的价值.方法 对82例子宫颈癌患者均行MRI检查.在MRI上观察病灶的部位、大小、信号特点、浸润范围、累及宫旁组织器官和淋巴结肿大等情况,根据MRI的影像表现进行分期.结果 82例患者中,Ⅰ期32例,其中Ⅰa期5例,Ⅰb期27例；Ⅱ期38例,其中Ⅱa期22例,Ⅱb期16例；Ⅲ期9例、Ⅳ期3例,其中Ⅲa期6例,Ⅲb期3例,Ⅳa期2例,Ⅳb期1例.结论 MRI能清楚地显示子宫颈癌病灶的浸润范围及是否转移,对子宫颈癌的MRI分期及治疗方法的选择均具有重要的价值.
