宫颈癌68例MRI分期与临床及病理分期的对比

目的 分析宫颈癌MRI表现,评价MRI成像对宫颈癌术前分期的价值.方法 68例经病理证实的宫颈癌患者,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,进行MRI影像分期,其中56例MRI术前分期与手术、病理分期对照.结果 68例MRI分期分别Ⅰa 2例,Ⅰb 5例,Ⅱa 34例,Ⅱb 12例,Ⅲa 4例, Ⅲb 5例,Ⅳa 4例,Ⅳb 2例.MRI在判断宫颈癌发生部位的准确率为100%,判断宫旁浸润的准确率为86.7%,判断宫颈癌总的分期准确率为88%.结论 MRI能清楚显示宫颈癌病灶的侵犯范围,对宫颈癌的分期价值极高,对临床制定治疗方案及预后评估有重要意义,建议对宫颈癌患者进行常规检查.Abstract：Objective To analyze the MRI features of cervical carcinoma,and evaluate the value of MRI in staging of cervical carcinoma. Methods Pelvic MRI imaging was performed in 68 patients with cervical carcinoma proved by pathology.MRI images were analyzed for location,size,signal characteristics,extension of the primary tumor and surrounding tissue. MRI findings were compared with clinical staging and surgical pathologic findings.Results Based on MRI staging,stage Ⅰa was seen in 2 cases,Ⅰb in 5 cases,Ⅱa in 34 cases,Ⅱb in12 cases,Ⅲa in 4 cases,Ⅲb in 5 cases,Ⅳa in 4 cases,Ⅳb in 2 cases. The accuracy of MRI imaging in determination of tumor location was 100%, invasion the parauterine tissue was 86.7%. The total accuracy of MRI imaging staging was 88%.Conclusions MRI can well demonstrate the size and extension of the cervical carcinoma, MRI has important value in staging of cervical carcinoma,and very helpful in making the therapeutic plan.It is suggested that MRI should be regarded as a conventional study for the patients with cerivical carcinoma.
