Does Size Matter? Agreement in Pancreatic Cyst Size Between EUS, CT, and MR

Abstract

METHODS. A retrospective chart review was performed on all patients presenting to a tertiary referral center from 2000-08 for EUS evaluation of pancreatic cystic lesions. The largest one-dimensional cyst diameters from CT, MRI/MRCP, and EUS reports were collated. Measurements from surgical pathology, when available, were included for comparison. Eligible patients had two or more size estimates from studies occurring within 90 days of each other. Differences in cyst diameter were calculated between available imaging studies and between imaging and surgical path.
