低场MRI在宫颈癌诊断及分期中的应用价值

Application Value of Low-field MRI in Cervical Cancer Diagnosis and Staging

目的探讨低场磁共振成像(MRI)在宫颈癌诊断及分期中的临床应用价值。方法对150例宫颈癌患者进行螺旋CT、低场MRI检查,分析肿瘤在MRI上的影像学表现,比较CT与MRI检查宫颈癌的阳性率、准确率以及肿瘤MRI分期与手术病理分期的吻合率。结果低场MRI对宫颈癌诊断的阳性率及准确率均显著高于螺旋CT,与对宫颈癌的临床分期相比,低场MRI分期与病理分期的符合率显著增高,差异有统计学意义(P<0.01)。结论低场MRI对宫颈癌诊断及分期的准确率均较高,具有重要的诊断及指导治疗的意义。

Objective To investigate the clinical value of low field MRI applications in cervical cancer diagnosis and staging. Methods A retrospective analysis of 150 cases of cervical cancer patients who received spiral CT, low field MRI were done, imaging findings of MRI were analyzed, CT and MRI positive rate and accuracy, and MRI staging and pathological staging matching rate were compared. Results The positive rate and accuracy of the low-field MRI of cervical cancer diagnosiswere significantly higher than the spiral of CT, as for the staging,low-field MRI staging and pathological staging match rate was significantly higher （ P 〈 0.01 ）. Conclusion The accurate rates of diagnosis and staging of cervical cancer of low-field MRI are high, which is of great significance for the diagnosis and guiding the treatment.
