摘要
目的:探讨常规磁共振成像(MRI)平扫结合弥散加权成像(DWI)在宫颈癌分期和病理特征等方面的价值。方法:选取宫颈癌患者56例,行MRI平扫及DWI序列扫描并且测量表观扩散系数(ADC)。将临床妇科检查、MRI、MRI联合DWI分期与术后病理分期比较,分析宫颈癌病理类型、宫颈鳞癌分化程度、宫颈鳞癌分期与ADC值的关系。结果:对Ⅰ_b期、Ⅱ_a期的诊断,MRI平扫结合DWI最具优势,宫颈鳞癌的平均ADC值小于腺癌,鳞癌随着分化程度的增高平均ADC值增加,以上结果差异均具有统计学意义(P<0.05),对宫颈鳞癌Ⅰ_a、Ⅰ_b、Ⅱ_a期三组平均ADC值进行方差分析,差异无统计学意义(P>0.05)。结论:MRI联合DWI对宫颈癌的分期最有优势,ADC值对宫颈癌病理类型及鳞癌的分化程度具有指导作用,但是对鳞癌的病理分期无价值。
Objective:To evaluate the value of MRI scan combined DWI in in the staging,pathological features and other aspects of cervical cancer. Methods:A total of 56 cases of cervical cancer were selected,which were conducted by MRI and DWI scans. Apparent diffusion coefficient(ADC)values were measured. Comparison of clinical, MRI,MRI scan combined DWI staging and postoperative pathological staging was performed. Analysis of the relationship between cervical cancer pathological type,cervical squamous cell carcinoma differentiation degree,cervical squamous cell carcinoma staging and ADC value was made. Results:The accuracy rate of MRI combined with DWI on Ⅰb and Ⅱa staging was the highest. The average ADC value of cervical squamous cell carcinoma was smaller than the adenocarcinoma. The average ADC values of squamous carcinoma patients increased gradually with the increasing of the degree of differentiation. All of the above results were P 〈 0. 05. The average ADC values betweenⅠa ,Ⅰb and Ⅱa were compared and the result was P 〉 0. 05. Conlusion:MRI combined with DWI on the staging of cervical cancer has the most advantage. The ADC value can help to differentiate the pathological type and degree of cervical squamous cell carcinoma. ADC value has no value on the pathological staging of squamous cell carcinoma.
