摘　　要：目的探讨多层螺旋CT(MSCT)与磁共振成像(MRI)诊断胰腺神经内分泌肿瘤(pNENs)及其对病理分级的临床价值。方法回顾性分析2015年6月至2018年6月安阳市肿瘤医院收治的64例pNENs病人临床资料,所有病人均行MSCT、MRI检查。以病理检查作为金标准,评估不同影像学检查诊断pNENs的准确性及评估不同病理分级的价值。结果①MSCT与MRI诊断pNENs的总体检出率(87.50%比89.06%)、敏感性(83.82%比85.29%)对比,均差异无统计学意义(P>0.05);②不同级别pNENs的直径、病灶边缘、病灶形状、主胰管扩张和远处转移比例对比,均差异有统计学意义(P<0.05);不同级别pNENs部位和囊变坏死比例对比,差异无统计学意义(P>0.05);MSCT影像表现中,不同级别pNENs动脉期和门脉期CT绝对强化值对比,差异有统计学意义(P<0.05);MRI影像表现中,不同级别pNENs动脉期和门脉期高信号比例对比,差异有统计学意义(P<0.05)。结论MSCT与MRI均能有效诊断pNENs,评估其病理分级。Objective To explore the clinical value of multi-slice spiral CT(MSCT)and magnetic resonance imaging(MRI)in the diagnosis of pancreatic neuroendocrine neoplasms(pNENs)and pathological grades.Methods The clinical data of 64 patients with pNENs admitted to Anyang Tumor Hospital between June 2015 and June 2018 were retrospectively analyzed.All patients underwent MSCT and MRI examination.Pathological examination was used as the gold standard to evaluate the accuracy of different imaging examinations in the diagnosis of pNENs and to evaluate the value of different pathological grades.Results There were no statistically significant differences in the overall detection rate(87.50%vs.89.06%)and sensitivity(83.82%vs.85.29%)of MSCT and MRI(P>0.05).There was no significant difference in the proportions of diameter,lesion margin,lesion shape,main pancreatic duct dilatation and distant metastasis of pNENs at different grades(P<0.05).There were no significant differences in the proportions of sites and cystic necrosis of pNENs at different grades(P>0.05).In MSCT imaging,there were statistically significant differences in the CT absolute enhancement value of pNENs arterial phase and portal phase(P<0.05).In MRI imaging,there was a statistically significant difference in the proportion of high signal in pNENs arterial phase and portal phase(P<0.05).Conclusions MSCT and MRI can effectively diagnose pNENs and evaluate the pathological grades.
