1.5T超导磁共振DWI序列在胰腺良恶性病变中的临床应用

目的评价1.5T超导磁共振弥散成像(DWI)在胰腺良恶性肿块诊断中的应用价值。方法对35个胰腺病变进行DWI检查,分析胰腺癌与良性慢性肿块型胰腺炎ADC值的差异。结果良性慢性肿块型胰腺炎与胰腺癌在分子扩散方面存在差异,ADC值是鉴别胰腺病变性质的有效参数。结论 DWI对胰腺癌及良性慢性肿块型胰腺炎鉴别具有价值,是对常规磁共振的有益补充。

Objective To evaluate the value of diffusion-weighted imaging（DWI）in distinguishing between MR imaging of Pancreatic carcinoma and chronic mass-forming type pancreatitis.Methods Thirty five patients of Pancreatic pathological changes under DWI.The computed InearI apparent diffusion coeffi cients（ADC）of the Pancreatic carcinoma and Chronic mass-forming panereatitis.Results There was obviously difference in molecules diffusion between Pancreatic carcinoma and Chronic mass-forming pancreatitis.The ADC would be an effective parameter in distinguishing between Pancreatic carcinoma and Chronic mass-forming pancreatitis.Conclusion DWI is valuable for differentiate Pancreatic carcinoma and Chronic mass-forming pancreatitis.And is a useful supplewentfor conventional MRI examination.
