T1433: MRCP vs. EUS-FNA: What Is the Best Way to Diagnosis and Classification (Type and Extent) of IPMT?

Abstract

Intraductal papillary mucinous tumors of the pancreas are being diagnosed with increasing frequency. CT scanning commonly serves as the primary imaging modality before surgery. The MRCP provides better characterization of IPMT type/extent, which more closely matches actual pathology. The endosonography-guided fine needle aspiration (EUS-FNA) has been increasingly used in order to make the histological diagnosis preoperatively, and to determine the type and extent of this tumor. The aim of this study is to compare the results of MRCP and EUS-FNA for the diagnosis and classification of IPMT with surgical and pathological findings.
