胰腺导管内乳头状黏液肿瘤的影像学研究现状及进展

目的总结胰腺导管内乳头状黏液肿瘤(IPMN)的影像学研究现状及进展。方法检索PubMed、中国知网、维普、万方等数据库内与胰腺IPMN相关的影像学研究方面的文献并进行分析与总结。结果现在常用于胰腺IPMN检查的影像学方法包括CT、MRI、EUS及PET-CT,其中CT和MRI有较好的诊断及鉴别良恶性胰腺IPMN的能力,并且MRI与新型靶向纳米粒子造影剂一起可以用于早期胰腺IPMN的诊断;EUS对于发现胰腺IPMN的壁结节很有优势,但其对于胰腺IPMN的诊断分级能力是否比得上CT、MRI尚有争论;PET-CT主要是对于胰腺IPMN良恶性诊断有较高的价值。结论目前各种影像学方法在胰腺IPMN诊断及良恶性鉴别方面都有各自的优势,在条件允许情况下首选MRI检查。

Current status of intraductal papillary mucinous neoplasms of pancreas in imaging

Objective To summarize the current status of imaging in intraductal papillary mucinous neoplasms of the pancreas(IPMN).Method The related literatures of imaging about IPMN of the pancreas were searched in the PubMed,CNKI,VIP,and Wanfang Data databases,etc.Results A variety of imaging techniques could be used to diagnosis IPMN of the pancreas,including CT,MRI,EUS,and PET-CT.The CT and MRI had great performances to diagnose and differential diagnosis of benign and malignant IPMN of the pancreas.The MRI with new targeted nanoparticle contrast agents could be used to diagnosis the early IPMN of the pancreas.The EUS was very good at detecting the wall nodules in the IPMN of the pancreas.Compared with the CT and MRI,the ability of EUS to grade IPMN of the pancreas was uncertain.The PET-CT was of high performance for the differential diagnosis between the benign and malignant IPMN of the pancreas.Conclusions Various imaging technologies have their own advantages in diagnosing IPMN of pancreas.MRI is currently the optimal choice when condition is permit.
