功能性胰岛素瘤的MSCT诊断

目的：讨论胰岛素瘤的MSCT诊断及检查技术要点。方法：对6例胰岛素瘤患者行多排螺旋CT多期薄层增强扫描，用100ml非离子型造影剂，高压注射器流速3．0ml／s，动脉期延迟（30±5）s，胰腺期延迟（45＋5）s，门脉期延迟（70±5）S。结果：6例全部在动脉期表现为高密度，胰腺期4例呈高密度，门脉期全部呈等密度表现。结论：MSCT增强扫描对胰岛素瘤的诊断具有较高的价值。

MSCT diagnosis of functional insulinoma

Objeetive： To discuss the MSCT diagnosis and screening techniques of insulinoma. Methods： Six cases of patients with insulinoma were performed multi-slice spiral CT scanning enhanced multi-phase thin-layer. 100 ml non-ionic contrast agent was used, and the injector flow rate was 3.0 ml/s. The arterial phase delay was （30±5） s, the pancreatic phase was （45±5） s, and the portal phase was （70±5） s. Results： All the six patients showed high-density in the arterial phase, four patients showed high-density in the pancreatic phase, all the six patients showed iso-dense in portal phase. Conclusion： Enhanced MSCT presents high value in the diagnosis of insulinoma.
