胰岛细胞瘤的CT和MRI表现

CT and MRI features of pancreatic islet cell tumors

目的:探讨胰岛细胞瘤的CT和MRI表现。方法:对9例手术证实的胰岛细胞瘤的CT和MRI表现进行回顾性分析,其中功能性胰岛细胞瘤7例,无功能性胰岛细胞瘤2例。结果:9例胰岛细胞瘤均富血供,边界清楚,与周围胰腺分界清楚,无血管、胰管侵犯。功能性胰岛细胞瘤多较小,无功能性胰岛细胞瘤较大。结论:胰岛细胞瘤有典型的CT和MRI表现,CT和MR增强扫描能准确诊断胰岛细胞瘤。

Objective： To analyze the CT and MRI features of pancreatic islet cell tumors. Methods： CT and MR images of 9 patients with pancreatic islet tumor confirmed by pathology were analyzed, among which 7 are functional islet cell tumors and 2 nonfunctional.Results：9 pancreatic islet cell tumors were all hypervascular with clear margin, no blood vessel and pancreatic duct infiltration. Functional islet cell tumors usually are small,but nonfunctional islet cell tumors usually are big. Conclusion： CT and MRI features of Pancreatic islet cell tumors are typical, CT and MR scan with contrast can correctly detect pancreatic islet cell tumor.
