摘　　要：目的探讨胰腺动态容积CT（DVCT）检查对胰岛素瘤的诊断价值。方法对23例具有典型Whipple三联征、临床诊断为胰岛素瘤的患者进行320层VDCT检查；分析DVCT对胰岛素瘤的定位、定性诊断价值。结果23例患者DVCT共检出23枚胰腺结节性病灶（胰头及钩突6枚，胰体10枚，胰尾7枚），直径为1．1—3．4（1．7±0．5）cm，病灶均表现为富血供强化结节。21例手术治疗者得到病理证实，2例未行手术治疗。与手术病理对照，DVCT的胰岛素瘤定位准确率达到100％。结论胰腺DVCT成像能保证对胰岛素瘤强化动态过程的连续观察，对胰岛素瘤治疗前诊断具有重要价值。Objective To investigate the diagnostic value of dynamic volume CT （DVCT） in insulinomas. Methods Twentythree patients with characteristic Whipple＇ s triad were examined with a 320-slice DVCT; the imaging performance and the value of DVCT in the diagnosis and the localization of insulinomas were evaluated retrospectively. Results In 23 patients, 6 tumors in pancreatic head or isthmus, 10 tumors in pancreatic body and 7 tumors in pancreatic tail were found with DVCT as rich blood nodules in pancreas. The mean size was （ 1.7 ± 0.5） cm （ 1.1 - 3.4 cm）. And 21 cases of insulinomas were confirmed by postoperative pathology, and 2 cases suspected of insulinoma did not accepted operation. Compared with surgical pathology, DVCT achieved a positively detected rate of 100% in the 21 cases of insulinomas. Conclusion With a volume, dynamic acquisition mode, DVCT is of important value in the diagnosis of insulinoma, by continuously observing for tumor enhancement after contrast agent injection.
