胰腺内分泌肿瘤磁共振影像学特征

Features of magnetic resonance imaging of pancreatic endocrine tumors

摘要:
胰腺内分泌肿瘤是一种少见肿瘤，分为功能性和无功能性两大类，临床表现各异，容易漏诊和误诊。随着MRI技术的发展，特别是脂肪抑制技术、弥散加权成像扫描(DWI)及动态增强MRI扫描的应用，对胰腺内分泌肿瘤的影像学诊断及鉴别诊断具有重要价值。本研究回顾性分析2007年6月至2011年12月湖北省恩施土家族苗族自治州中心医院收治的13例胰腺内分泌肿瘤患者的临床资料，旨在总结该病的MRI检查表现特征，评价MRI检查特别是DWI和动态增强扫描对胰腺内分泌肿瘤的诊断价值。

Abstract: Pancreatic endocrine tumors (PETs) are very rare and are divided into functional and nonfunctional tumors. Their clinical manifestations vary, and imaging diagnosis easily led to missing diagnosis and misdiagnosis for PETs. With the development of MRI technology, especially application of fat suppression techniques, diffusion weighted imaging (DWI) and dynamic enhanced magnetic resonance imaging (DEMRI) are of great value on imaging diagnosis and differential diagnosis for PETs. The clinical data of 13 patients with PETs who were admitted to the Central Hospital of Enshi Autonomous Prefecture from June 2007 to December 2011 were retrospectively analyzed, and their MRI imaging features were studied. The diagnostic values of MRI, especially DWI and DEMRI for PETs were investigated.
