胰腺内分泌肿瘤的影像学分析

Imaging Analysis of Pancreatic Endocrine Neoplasms

目的对比分析胰腺内分泌瘤CT、MRI影像学特征,总结定性诊断经验。方法以33例PET患者作为研究对象,对CT、MRI影像学特征进行描述性统计。结果高分化肿瘤14例、高分化内分泌癌18例、低分化内分泌癌1例,良性病灶最大直径(37.5±14.2)mm低于恶性病灶(48.4±12.0)mm,良性病灶界限清楚、强化均匀比重高于恶性,差异具有统计学意义(P<0.05)。结论 CT、MRI在胰腺内分泌肿瘤定性诊断中均具有一定价值,CT、MRI可优势互补,提高PET定位诊断水平。

Objective Comparative analysis of pancreatic endocrine tumors CT, MRI imaging features,summarize the qualitative diagnosis experience. Methods 33 cases of PET patients as the research object, the CT, MRI imaging features were analyzed by descriptive statistics. Results 14 cases of high differentiated tumors, 18 cases of high differentiated neuroendocrine carcinoma, poorly differentiated endocrine carcinomas in 1 case, the largest diameter of benign lesions（37.5±14.2） mm lower than that of malignant lesions（48.4±12） mm, benign lesions clear boundaries, strengthening uniform proportion is higher than that of malignant, the differences were statistically significant（P〈0.05）. Conclusion CT, MRI has a certain value in qualitative diagnosis of pancreatic neuroendocrine tumor, CT, MRI can be complementary advantages, improve the diagnosis level of PET positioning.
