Mo1286 PREDICTING MALIGNANCY RISK IN GASTROINTESTINAL SUBEPITHELIAL TUMORS WITH CONTRAST-ENHANCED HARMONIC ENDOSCOPIC ULTRASOUND USING A PERFUSION ANALYSIS SOFTWARE

Contrast enhanced harmonic endoscopic ultrasound (CEH EUS) is a promising imaging modality that can identify subepithelial tumors (SETs) by detecting the degree of enhancement, but whether CEH EUS alone can predict the malignancy risk of gastrointestinal stromal tumors (GISTs) remains unclear. The aim of our study was to evaluate the ability of CEH EUS using a perfusion analysis software for the discrimination among SETs and the prediction of malignancy risk of GISTs.
