| 摘 要： | 对13例自身免疫性胰腺炎(AIP)患者的磁共振影像(MRI)资料作回顾性分析.结果 显示,13例中10例见胰腺弥漫性肿大、3例局限性肿大.13例平扫病变区均为T2WI稍高、T1WI低信号,1l例于病变区胰周见增厚的T1WI等低、T2WI低信号包膜样结构;增强后病变区及包膜样结构呈延迟强化;10例见胆总管胰腺段狭窄及其以上胆管扩张;9例糖皮质激素治疗后MRI复查者均明显好转. |

| Abstract: | The MRI data of 13 patients with autoimmune pancreatitis (AIP) were retrospectively analyzed. The results showed that the pancreas diffusely enlarged in 10 of 13 cases, and focally enlarged in 3cases. There were 13 cases with decreased signals on T1WI and mildly hyperintense on T2WI in the area with pancreatic lesions, 11 cases with thickened capsule-like structure showing moderate-low signal T1WI and low signal T2WI,and delayed enhancement in dynamic contrast-enhanced MRI, and 10 cases with stenotic common bile duct at the level of pancreas with proximal cholangiectasis. The findings in 9 cases were remarkably improved in followup MRI after glucocorticord treatment. |
