摘要 目的探讨胰腺神经内分泌肿瘤(P-NET)的MRI特征。方法选择我院胰腺神经内分泌肿瘤患者32例,术前均进行上腹部MRI平扫与增强扫描,分析MRI临床表现。结果32例患者均为单发,病理分级中G1级13例,G2级18例,G3级1例,其中囊性病灶为2例,实性病灶为30例。32个病灶均可在MRI上清晰显示,所有病灶直径均为0.8~8.2cm,平均病灶为(3.58±1.25)cm;其中类圆形病灶为25个,不规则病灶为27个。G1级患者在直径上低于G2级患者,且在形状、边缘、胰腺外侵犯、主胰管扩张、淋巴结和肝转移上均存在明显差异,G1级患者为圆形、清晰、出现胰腺外侵犯、主胰管扩张、淋巴结和肝转移较少;在平扫信号强度上,G1级患者均质为9例(69.23%),G2级为7例(38.89%),在增强扫描中动脉期、胰腺期、门静脉期、延迟期G1级患者均为等、高信号,而G2级患者均为低信号;差异显著,P<0.05。结论P-NET不同病理分级患者的MRI特征存在一定差异,临床可通过MRI特征进行诊断。
