B超、CT、MRI对宫颈癌的诊断价值对比分析

Comparative analysis of diagnostic value of imaging of cervical cancers by B-ultrasonography,CT and MRI

目的:探讨B超、CT、MRI 3种检查方法对女性子宫颈癌的诊断价值,以期找到子宫颈癌早期诊断的最佳方法。方法:对120例已行B超、CT、MRI检查并经病理证实的子宫颈癌进行分析,以病理检查为金标准,对比这3种方法的检出正确率。结果:3种检测方法的检出正确率依次为:B超77.5%、CT 82.5%、MRI 94.2%。结论:MRI检出准确率最高;CT对、期病变的检出准确率低于MRI,对、期病变的检出准确率与MRI对比无明显差异。

Objective： To explore the diagnostic value of imaging of cervical cancers by B-ultrasonography, CT and MRI for the best method of the early diagnosis of the cervical, cancer. Methods ： 120 cases of cervical cancers imaged by B-ultrasonography, CT and MRI, and pathologically diagnosed, were analyzed. A contrast of correctness in the images by B-ultrasonography, CT and MRI based on the pathological diagnosis were also analyzed. Results： A correctness of 77.5% in B-ultrasonography, 82.5% in CT, 94.2% in MRI; the diagnostic accuracy of the collapses in the fist and second stages by CT was lower than that by MRI, and the diagnostic accuracy of the collapses in the third and fourth stages by CT was not significant difference from that by MRI. Conclusions ： The diagnosis rate by B- ultrasonography is the lowest, but it can be the first choice for diagnosis of cervical cancers; the diagnosis rate by MRI is the highest, and the combination of B-ultrasonography and MRI or CT and MRI have a marked rise in the diagnostic accuracy of the cervical cancer.
