Prediction of intraoperative bleeding during endoscopic treatment in patients with early gastric cancers: utility of contrast-enhanced MDCT gastrography and the wall-carving image technique.

Purpose To assess the ability of the “wall-carving image (WC) technique,” which uses vascular images from computed tomography (CT) gastrography, to predict bleeding during endoscopic treatment in patients with early gastric cancers (EGC).
