摘要
[目的]应用高b值磁共振扩散加权成像（DWI）及表观弥散系数（ADC）分析宫颈癌相关病理学特征。[方法]49例病理证实的宫颈癌患者以及19人正常宫颈健康志愿者的常规MRI平扫、DWI、ADC图像,b值取700s/mm2,比较宫颈癌组与正常宫颈组ADC值。[结果]b=700s/mm2时正常宫颈黏膜层、结合带、肌层及宫颈全层ADC值分别为（1.717±0.132）×10^（-3）mm2/s、（1.391±0.106）×10^（-3）mm2/s、（1.956±0.217）×10^（-3）mm2/s、（1.613±0.145）×10^（-3）mm2/s,差异有统计学意义（P〈0.05）。宫颈癌组ADC值为（0.912±0.140）×10^（-3）mm2/s,显著性低于正常宫颈（P〈0.05）。鳞癌ADC值为（0.882±0.103）×10^（-3）mm2/s,腺癌ADC值为（1.047±0.165）×10^（-3）mm2/s,两组差异有统计学意义（t=-3.985,P=0.000）。角化性大细胞型组与非角化性大细胞型组ADC值差异无统计学意义。[结论]DWI及其量化参数ADC值有助于鉴别宫颈癌与正常宫颈以及评估宫颈癌的病理类型。
[Objective] To assess the application of high b value MR diffusion weighted imaging（DWI） and apparent diffusion coefficient（ADC） in prediction of pathological features in cervical cancer patients. [Methods] Data of MRI,DWI and ADC were collected from 49 cases of cervical cancer confirmed pathologically and 19 healthy subjects. The ADC values at b value of 700 s/mm2 were compared between cervical cancer patients and controls. And the correlation between ADC values and pathological features in cervical cancer patients was analyzed. [Results] At b value of700 s/mm2,the ADC values of normal mucosal layer,connective tissue layer,smooth muscle layer and full layer were（1.717±0.132）×10^（-3） mm2/s,（1.391±0.106） ×10^（-3） mm2/s,（1.956±0.217）×10^（-3） mm2/s,（1.613 ±0.145） ×10^（-3） mm2/s,respectively,and there was significant difference（P〈0.05）. The ADC values of cervical cancer patients was（0.912 ±0.140） ×10^（-3） mm2/s,which was significantly lower than that of control group（P〈0.05）. The ADC values of cervical squamous cell carcinoma and cervical adenocarcinoma were（0.882±0.103）×10^（-3） mm2/s and（1.047±0.165）×10^（-3） mm2/s（t=-3.985,P=0.000）;while there was no significant difference in the ADC values between the keratinocyte and the non-keratinocyte in cervical squamous carcinoma. [Conclusion] DWI and its parameter ADC may differentiate the cervical cancer from normal cervical tissues and may be used to differentiate the different pathological types of cervical cancer.
