摘　　要：目的 探讨功能性胰岛素细胞瘤的影像学表现。方法 对5例功能性胰岛素细胞瘤的病例术前进行B超、常规和动态团注增强CT扫描,其中1例进行脾动脉插管造影CT扫描检查,均经手术和病理证实。结果 B起示胰腺形态、大小无明显改变。CT扫描示动脉期与门静脉有瘤体明显强化,且持续时间长;脾动脉插管CT增强扫描易于肿瘤的显示。结论 对于有明显的临床低血糖综合征的患者,B超和MRI检查常不能很好的发现病灶,常规CT和薄层团注动态CT检查检出率较高。而对于直径小于1cm的肿瘤,应首选动脉插管造影CT检查。Purpose To evaluate imaging diagnosis of functional insulinoraa. Methods Five patients of functional insulinoma were examined by imaging techniques including ultrasound, pre - contrast and dynamic incremental bolus CT, which one of them underwent the computed tomography splenic angiography. All patients were confirmed by surgico - pathology. Results On ultrasound pancreatic shape and size were not changed clearly. Functional insulinoma is enhanced obviously and continuously during the period of artery and poital vein with CT.With CT splenic angiography, insulinoma was displayed more easily. Conclusions Conventional CT and dynamic incrementa bolus CT can detect the functional insulinoma sensitively. For insulinoma of which the diameter is below 1 centimetre, splenic angiographic computed tomography must be the first choice.
