目的：探讨高场强 MRCP 在胰腺导管内乳头状黏液瘤(IPMNs)的应用价值。方法收集15例经手术病理证实的IPMNs 患者,回顾性分析其 MRI 表现,重点探讨 MRCP 的诊断价值。结果15例均为良性,其中主胰管型1例,分支胰管型8例,混合型6例。主胰管型表现为主胰管弥漫扩张,直径约14.5 mm,增强后未见明确强化。分支胰管型表现为分支胰管呈单发囊状或多发簇状扩张,囊灶与主胰管相通,增强后分隔、壁结节呈“轻-中”度强化。混合型表现为主胰管与分支胰管不同程度扩张,强化特点与分支胰管型相同。结论高场强 MRCP 对 IPMNs 的分型诊断、病变范围观测有重要价值,结合动态增强 MRI,有助于良恶性的鉴别。

Objective To explore the value of high-field-strength MRCP in diagnosing of intraductal papillary mucinous neoplasms (IPMNs)of pancreas.Methods Fifteen cases with IPMNs confirmed surgically and pathologically were recruited.The magnetic res-onance imaging (MRI)and MRCP findings were retrospectively analyzed.Results All cases were benign,including main pancreatic duct type (MPD)in 1,branch pancreatic duct type(BPD)in 8,and the combined type in 6.The MPD type showed diffuse dilation of main pancreatic duct which is about 14.5 mm with no enhancement.The BPD type displayed unilocular or multilocular cystic le-sions which showed communication with main pancreatic duct .The combined type demonstrated dilation of main pancreatic duct and branch pancreatic duct.The septa and mural nodule in the BPD type and the combined type were moderately enhanced.Conclusion MRCP is superior with regard to the diagnosis and classification of IPMN type and is helpful to differentiate malignant tumors from benign ones combined with routine contrast-enhanced.
