【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(P0.05),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(P0.05)。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。
[Abstract]:Objective: To investigate the conventional magnetic resonance imaging (MRI) scan combined with diffusion weighted imaging (DWI) in cervical cancer staging and pathological feature value. Methods: 56 cases of patients with cervical cancer, underwent MRI scan and DWI sequence scanning and apparent diffusion coefficient measurement table (ADC). The clinical gynecological examination, MRI comparison, MRI staging and postoperative pathologic findings combined with DWI analysis of cervical cancer staging, pathological type, degree of differentiation of cervical squamous cell carcinoma, the relationship between cervical squamous cell carcinoma staging and ADC. Results: on stage I _b, the diagnosis of stage II _a, MRI scan combined with DWI the most advantage, the average value is less than ADC in cervical squamous cell carcinoma. With the increase of the average degree of differentiation of ADC squamous cell carcinoma of the added value of the above results, the differences were statistically significant (P0.05), the cervical squamous cell carcinoma I _a, I _b, phase II _a three group of average ADC value variance analysis, the difference was not statistically significant (P0.05). Conclusion: MRI combined with DWI on the stage of cervical cancer Advantage, ADC value can guide the pathological type of cervical cancer and the degree of differentiation of squamous cell carcinoma, but it has no value to the pathological stage of squamous cell carcinoma.
