Abstract    Insulinoma is one of the most common pancreatic endocrine tumors. Surgical treatment is the only curative method. Whipple triad and the ratio of insulin to glucose are the key points for diagnosis of insulinoma.We can do the process of 72h fasting test if it is necessary.Non-invasive diagnostic methods are the first choice for localization of the tumors. In our hospital the improved MSCT has a high accuracy up to 95.1%. Combination IOUS and exploration has the highest accuracy up to 100%.Invasive diagnostic methods like DSA,PTPC and ASVS have seldom been used.This paper makes a evaluation and overview of the localization of insulinoma and is also as a reference for clinic work.
