A Deep Learning Model for Diagnosing Gastric Mucosal Lesions Using Endoscopic Images: Development, Validation, and Method Comparison


Endoscopic differential diagnoses of gastric mucosal lesions remain challenging. We aimed to develop and validate convolutional neural network-based artificial intelligence models-lesion detection, differential diagnosis, and invasion-depth models. The AI-DDx showed good diagnostic performance for both internal and external validation. The performance of the AI-DDx was better than that of the novice and intermediate endoscopists, but was comparable to the experts in the external validation set. The AI-ID showed fair performances in both internal and external validation sets, which were significantly better than EUS results performed by experts.
