目的：总结神经内分泌肿瘤的影像学特点，提高诊断的准确性。方法回顾性分13例经手术病理证实的神经内分泌肿瘤的患者,分析其临床及影像学特点，旨在提高对该类肿瘤的诊断准确性。结果13例病例中，位于胰腺的8例，纵膈2例，胃肠道3例，最大径平均值为3.5cm，13例均伴有不同程度囊变坏死。其中MRI检查有8例，均位于胰腺，T1WI为等或低信号，T2WI为混杂高低信号，DWI均为高信号。CT检查有5例，位于纵膈及胃肠道，平扫为等低混杂密度，平扫实性部分CT值平均值为46.3HU。增强扫描CT及MRI检查均呈“快进快出”表现，囊变坏死区无强化。结论神经内分泌肿瘤表现多种多样，多个部位均可发生，影像学具有一定特征性，确诊需要病理学诊断。

Objective To summarize the characteristics of neuroendocrine tumor images, improve the accuracy of diagnosis. Methods 13 cases of neuroendocrine tumors were proved by operation and pathology characteristics of patients, the clinical and imaging analysis, in order to improve the accuracy of diagnosis of this tumors. Results In 13 cases, 8 cases were located in the pancreas, 2 cases mediastinum, 3 cases of gastrointestinal tract, the maximum diameter of the average value is 3.5cm.13 cases were accompanied with different degree of cystic necrosis. The MRI examination in 8 cases were located in the pancreas, T1WI showed low signal, T2WI showed mixed high and low signal, DWI showed high signal. CT examination had 5 cases, they were located in the mediastinum and the gastrointestinal tract, scan for lower hybrid density, plain and solid part of the average CT value of 46.3HU. Enhanced CT scan and MRI examination showed obviously Enhanced and no enhancement in cystic necrotic area. Conclusion The manifestation of neuroendocrine tumors are varied, multiple parts may occur.Imaging had some characteristics, but diagnosis required pathology diagnosis.
