胰岛素瘤的定位诊断进展

Research Progress on Niveau Diagnosis of Insulinomas

胰岛素瘤的诊断主要分为定性诊断和定位诊断。定位诊断主要通过影像学方法和一些特异性的功能试验。由于胰岛素瘤属富血运肿瘤,增强CT或磁共振成像是比较常用的方法。超声造影是一种新的定位方法,具有敏感度高、损伤小等优点。术中超声是手术中定位的主要方法。一些特异性的功能试验由于损伤较大,现已较少采用。

The diagnosis of insu｜inomas includes qualitative diagnosis and niveau diagnosis. The later usually depends on imaging method and some specific functional tests. Contrast-enhanced CT and MRI are usually usod to localize insulinomas,for the insulinomas appears hypervascular at imaging. Contrast-enhanced uhrasonogrphy can show insulinomas clearly. Uhrasonography is a new imaging method with higher sensitivity and trivialer injury than other methods. Intraoperative ultrasound is a mainly locating method during operation. Some specific tests are rarely used in recent years due to serious injury in medical examination.
