In 41 patients with clinical evidence of pancreatic islet cell tumors, CT detected 21 of 27 tumors that were proved at surgery (sensitivity 78%) and correctly excluded the diagnosis in 14 of 14 patients with no evidence of tumor at long-term follow-up. Using rapid sequence CT scanning and bolus contrast material infusion, a vascular blush was identified in 13 of 16 tumors (81%). Tumors as small as 0.9 cm were localized. CT identified all malignant tumors, and staging accuracy was 100%. CT is useful as the initial imaging procedure for the diagnosis and staging of suspected islet cell tumors. Pancreatic venous sampling and angiography are complementary to CT for the detection of smaller lesions.
在41例有胰岛细胞瘤临床证据的患者中，CT检测出27例手术证实的肿瘤中的21例（敏感性78%），并在14例长期随访无肿瘤证据的患者中正确排除了诊断。使用快速序列CT扫描和团注造影剂，16例肿瘤中的13例（81%）发现了血管造影剂外溢。小至0.9 cm的肿瘤也能定位。CT识别出了所有恶性肿瘤，分期准确率为100%。CT作为疑似胰岛细胞瘤诊断和分期的初始影像学检查方法很有用。胰腺静脉采血和血管造影对CT检测较小病变具有互补作用。
