总结经ＣＴ与胃肠钡餐低张造影检查并经手术及病理证实的无功能胰细胞瘤１６ 例， 分析其ＣＴ与胃肠钡餐低张造影的征象。指出典型的无功能胰岛细胞瘤瘤体较大， 对周围脏器有推压征象。ＣＴ平扫为稍低密度肿块病变， 大多数病例瘤体内可有不同程度的钙化， 造影增强后病变无明显强化， 其包膜有间断的不规则增强。胃肠钡餐低张造影对鉴别胃肠源性肿块也有重要意义。
Summarized 16 cases of non-functioning pancreatic tumors confirmed by CT and gastrointestinal barium meal underwent angiography and confirmed by surgery and pathology. The CT and gastrointestinal barium meal underwent low-contrast imaging. It is pointed out that the typical nonfunctioning islet cell tumor has a large tumor and there are push signs on the surrounding organs. CT plain scan is a slightly low-density mass lesion. In most cases, the tumor may have different degrees of calcification in the body. After the contrast enhancement, the lesion is not significantly enhanced, and the capsule has an irregular and intermittent enhancement. Gastrointestinal barium meal angiography is also important for the identification of gastrointestinal lumps.
