Representative images of correctly or incorrectly determined lesions by the deep-learning (DL) algorithm. (a): Wrong answer case by the DL algorithm in endoscopically resected lesions (moderately differentiated adenocarcinoma with SM2 invasion); (b): wrong answer case by the DL algorithm in endoscopically resected lesions (well differentiated adenocarcinoma with SM3 invasion); (c): correct answer case by the DL algorithm for endoscopic submucosal dissection (ESD) candidate in surgically resected lesions (mucosa-confined signet ring cell carcinoma with 1 cm diameter); (d): wrong answer case by the DL algorithm in surgically resected lesions (mucosa-confined poorly differentiated adenocarcinoma within expanded indication); DL, deep-learning; ESD, endoscopic submucosal dissection.
