CT与MRI在宫颈癌术前分期诊断中的应用价值分析

Application value of CT and MRI in the preoperative staging diagnosis of cervical cancer

目的探讨X线计算机体层(CT)与磁共振成像(MRI)在宫颈癌术前分期诊断中的应用价值。方法选取2013年3月~2016年12月在我院就诊的47例宫颈癌患者,于术前1周行CT、MRI检查,并以病理诊断结果为金标准,分析CT和MRI在宫颈癌术前分期诊断中的应用价值。结果经病理确诊,47例宫颈癌患者中ⅠB_1期及以下16例,ⅠB_2~ⅡA期22例,ⅡB期及以上9例,且盆腔淋巴结转移阳性16例,子宫体侵犯阳性11例,阴道浸润阳性20例;MRI诊断ⅠB_1期及以下的符合率明显高于CT诊断,差异有统计学意义(P<0.05);CT诊断盆腔淋巴结转移的特异性、准确性及子宫体侵犯的准确性均显著高于MRI诊断,差异有统计学意义(P<0.05);MRI诊断阴道浸润的敏感性及准确性均高于CT诊断,差异有统计学意义(P<0.05)。结论 MRI诊断ⅠB_1期及以下宫颈癌及阴道浸润情况效果显著,而CT诊断盆腔淋巴转移及子宫侵犯情况效果较好。

Objective To investigate the application value of computed tomography （CT） and magnetic resonance imag- ing （MRI） in the preoperative staging diagnosis of cervical cancer.Methods 47 patients with cervical cancer who admitted into our hospital and diagnosed from March 2013 to December 2016 were selected as the research object.All the patients were given CT and MRI examination before operation for one week,and the results of pathological diagnosis were taken as gold standard.The application value of CT and MRI in the preoperative staging diagnosis of cervical cancer was analyzed.Results According to the pathological results,there were 16 cases of ｜ B~ stage and below,22 cases of I B2- ]] A stage,9 cases of ]I B stage and above among 47 cases of patients with cervical cancer.At the same time,there were 16 cases of pelvic lymph node metastasis positive,11 cases of uterine invasion positive and 20 cases of vaginal infiltration.The accordance rate of I BI stage and below diagnosed by MRI was higher than that diagnosed by CT,and the difference had statistical significance （P〈0.05）.The specificity and accuracy of pelvic lymph node metastasis,the accuracy of uterine invasion diagnosed by CT were higher than those diagnosed by MRI,and the difference had statistical significance （P〈0.05）.The sensitivity and accuracy of vaginal infiltration diagnosed by MRI were higher than those diagnosed by CT,and the difference had statistical significance （P〈0.05）.Conclusion MRI in the diagnosis of cervical cancer （ I B1 stage and below） and vaginal infiltration has significant diagnostic effects,while the CT in the diagnosis of pelvic lymph node metastasis and uterine invasion has better diagnostic effects.
