Abstract

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.
