摘　　要：目的分析宫颈癌MR影像表现,评价MR在宫颈癌分期中的价值。资料与方法60例均在治疗前行盆腔的轴位SET1WI,轴位及矢状位快速自旋回波(TSE)T2WI。在MRI上观察肿瘤的位置、大小、信号特征、浸润范围及累及宫旁的情况,并将MR所见进行影像学分期,同时与临床及病理分期进行对比分析。结果MR在判断宫颈癌发生部位的准确性为100%,判断宫旁浸润的准确性为92.31%,判断宫颈癌分期总的准确性为96.67%,对宫旁浸润的特异性和敏感性分别为97.87%和92.31%。结论MR能多方位高分辨率显示宫颈癌病灶的位置、大小及向宫旁浸润的程度,对宫颈癌的分期具有极高的价值。临床检查结合MRI可较为准确地评价宫颈癌的分期,使其更接近于病理分期,从而对宫颈癌的治疗起到指导性的作用。Objective To explore the MR features of uterine cervical carcinoma, and evaluate the value of MR in staging of uterine cervical carcinoma. Materials and Methods Pelvic MR imaging was performed in 60 patients with cervical carcinoma proved by pathology. The MRI sequences included axial SE T1WI, axial and sagittal rISE T2WI. MR images were analyzed for location, size, signal characteristics, extension of the primary tumor and surrounding tissue. MR findings were compared with clinical staging and surgical pathologic findings. Results The accuracy of MR imaging in determination of tumor location was 100%, invasion the parauterine tissue was 92.31% . The specificity and sensitivity for parauterine extension were 97.87 % and 92.31%, respectively. The total accuracy of MR imaging staging was 96.67%. Conclusion MR imaging can show the location, size of tumors and extension of the cervical carcinoma clearly. MRI has important value in staging of uterine cervical carcinoma. The clinical examination combined with MRI scanning may evaluate the staging of cervical carcinoma accurately, which may guide the therapy of the cervical carcinoma.
