研究人员对 21 名高胰岛素血症患者进行了研究，以确定胰岛素产生的来源。十九名患者患有胰腺肿瘤，两名胰腺切除术后患者出现肝转移。在 19 例胰腺肿瘤中，有 16 例通过血管造影确诊。 CT 在研究的 14 名患者中发现了 6 个肿瘤，而超声检查仅正确定位了 12 个肿瘤中的 3 个。动脉造影阴性的患者 CT 和超声检查均未呈阳性。无创成像方法可以定位大肿瘤，并且可能有助于检测肝转移。然而，血管造影仍然是检测较小病变的最准确方法。
Twenty-one patients with hyperinsulinism were studied to localize the source of the insulin production. Nineteen patients had pancreatic tumors and two patients studied after pancreatectomy had hepatic metastases. Of the 19 pancreatic tumors, 16 were identified by angiography. CT found six tumors in 14 patients studied while sonography correctly localized only three of 12 tumors. Neither CT nor sonography was positive in those patients with a negative arteriogram. Noninvasive imaging methods can localize large tumors and may be useful for detecting hepatic metastases. Angiography, however, remains the most accurate method for detecting smaller lesions.
