256层CT对沟槽状胰腺炎的诊断价值

Diagnostic value of 256-slice CT in groove pancreatitis

目的探讨256层CT对沟槽状胰腺炎的诊断价值。方法对6例确诊为沟槽状胰腺炎患者的CT影像资料进行回顾性分析。结果 6例患者病灶均位于胰头和十二指肠之间,均表现为低密度影,增强后呈渐进性强化;患者均表现为不同程度十二指肠壁增厚,伴有周围渗出。结论沟槽状胰腺炎具有特征性的CT表现,有利于与胰头癌的鉴别诊断。256层CT以其超高的时间分辨率和密度分辨率,大大提高了沟槽状胰腺炎的检出率。

Objective To investigate the diagnostic value of 256-slice CT in groove pancreatitis（ GP）. Methods The CT image data of 6 patients with GP that was clinically confirmed were retrospectively analyzed. Results CT images showed a focus between the head of pancreas and duodenum in all the patients,the focus showed low density shadow,gradual enhancement after contrast-enhanced CT image. The thickening of duodenum wall with peripheral exudation was observed in all the patients at different degrees. Conclusion GP has distinctive CT manifestations,which is helpful for differential diagnosis of carcinoma of head of pancreas. The 256-slice CT greatly improves the detection rate of GP with its ultra high temporal resolution and density resolution.
