Mo1534 Examination of Feasibility of a Novel EUS Imaging Technique (Reversed 3D Imaging) in Pancreatico-Biliary Field

Abstract

Three-dimensional (3D) EUS imaging has been developed especially in combination with B-mode images and vasculature including color/power Doppler flow mapping. Recently, 3D imaging in combination with contrast-enhanced EUS (CE-EUS) has been also proposed. 3D images produced by simple manipulation of an endosonoscope inevitably lack the positional information, which is a limitation of 3D imaging regardless of its comprehensibleness. Reversed 3D imaging (R3DI) is the reversed display method between anechoic area and echogenic area with adjusting the threshold of an echogenicity.
