| 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 pa?tients with pNENs admitted to Anyang Tumor Hospital between June 2015 and June 2018 were retrospectively analyzed.All pa?tients underwent MSCT and MRI examination.Pathological examination was used as the gold standard to evaluate the accuracy ofdifferent 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 pan? creatic 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 signifi? cant 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).Con?clusions MSCT and MRI can effectively diagnose pNENs and evaluate the pathological grades. |
