目的 研究MR弥散加权成像参数 与宫颈癌肿瘤细胞组织学特点之间的相 关性。方法 临床纳入60例我院2014年1 月-2015年12月期间收治的宫颈癌患者， 均行MR弥散加权成像(DWI)临床检查，分 析评价系数ADC值与分化程度及肿瘤细胞 间质比例、病理类型等肿瘤细胞组织学 特点间的相关性。结果 宫颈癌患者ADC值 与肿瘤细胞间质比例、分化程度呈现一定 负相关性，而与病理类型呈现一定正相关 性(P＜0.05)；宫颈鳞癌组患者的ADC值较 宫颈腺癌组显著要低，高分化组患者ADC 值较低分化组患者显著要低(均P<0.05)； 肿瘤细胞间质比例≧70%组患者的ADC值显 著低于肿瘤细胞间质比例＜70%组，差异 具有统计学意义(P＜0.01)。结论 宫颈癌 肿瘤细胞组织学特点与MR弥散加权成像 (DWI)参数关系密切，可成为临床评估宫 颈癌预后、制定治疗方案的重要基础依 据。

Objective To study the MR diffusion weighted imaging parameters and cervical cancer tumor cells of the correlation between histological characteristics. Methods Clinical in 60 cases of cervical cancer patients admitted in our hospital during 2014.1 2015.12, all lines of MR diffusion weighted imaging (DWI) can clinical examination, analysis and evaluation coefficient of ADC values and the differentiation degree and the proportion of stromal tumor cells, pathological type and so on correlation between the histological characteristics of tumor cells. Results In patients with cervical cancer ADC values between tumor cells and mass ratio, degree of differentiation of present certain negative correlations, and characteristic to some positive correlation with pathological type (P<0.05). Cervical squamous carcinoma patients the ADC values of the cervical adenocarcinoma group was significantly lower, ADC values in patients with well-differentiated group patients was significantly lower in the poorly differentiated group (all P<0.05). Tumor cells interstitial ≧ 70% group of ADC values significantly lower than that of tumor cells in patients with interstitial proportion < 70% group, the difference statistically significant (P<0.01). Conclusions Cervical cancer tumor cells histological characteristics and parameters of MR diffusion weighted imaging (DWI) can close, can be a clinical evaluation of prognosis of cervical cancer, to develop the important basis for basis of treatment.
