Study the Value of 3.0T Magnetic Resonance Imaging in Diagnosing Pancreatic Neuroendocrine Tumors and Summarize Its Imaging Characteristics

目的:研究3.0T磁共振诊断胰腺神经内分泌肿瘤的诊断价值和影像学特点。方法:选择2022年10月~2023年7月到本院进行诊治的119例疑似胰腺神经内分泌肿瘤患者作为研究对象,在入院后所有患者均采用3.0T磁共振进行诊断,同时对所有患者开展病理检查,并且将其作为金标准,评价3.0T磁共振诊断胰腺神经内分泌肿瘤的价值,并总结其影像学特点。结果:①3.0T磁共振诊断胰腺神经内分泌肿瘤的阳性预测值为96.55%、阴性预测值为93.44%、敏感度为93.33%、特异度为96.61%、准确度为94.96%、约登指数为89.94%、误诊率为3.39%、漏诊率为6.67%;②3.0T磁共振诊断胰腺神经内分泌肿瘤具有独特的影像学特征。结论:3.0T磁共振诊断胰腺神经内分泌肿瘤所得的诊断结果与病理诊断结果相差无异,但是其诊断更加方便快捷,具有特征性的影像学特点和较高的诊断价值,能为临床的诊治工作提供科学的参考。

Objective:To study the diagnostic value and imaging characteristics of 3.0T magnetic resonance imaging in the diagnosis of pancreatic neuroendocrine tumors.Methods:119 patients suspected of pancreatic neuroendocrine tumors who were diagnosed and treated at our hospital from October 2022 to July 2023 were selected as the study subjects.After admission,all patients were diagnosed using 3.0T magnetic resonance imaging,and pathological examinations were performed on all patients,which were used as the gold standard to evaluate the value of 3.0T magnetic resonance imaging in diagnosing pancreatic neuroendocrine tumors and summarize their imaging characteristics.Results:①3.0T MRI for pancreatic neuroendocrine tumors has high diagnostic accuracy(94.96%),sensitivity(93.33%),and specificity(96.61%),with low misdiagnosis(3.39%)and missed diagnosis rates(6.67%).②The diagnosis of pancreatic neuroendocrine tumors using 3.0T magnetic resonance imaging has unique imaging features.Conclusion:The diagnostic results of 3.0T magnetic resonance imaging for pancreatic neuroendocrine tumors are similar to the pathological diagnosis,but its diagnosis is more convenient and fast,with characteristic imaging characteristics and high diagnostic value,which can provide scientific reference for clinical diagnosis and treatment.
