As an emerging technology,artificial intelligence(AI)has brought great changes to the precise diagnosis of inflammatory bowel disease(IBD).More and more researches have developed diagnostic models which are based on machine learning(ML)and deep learning(DL)and obtained satisfactory diagnostic performance.Especially in the image diagnosis of IBD,convolutional neural network(CNN)and other models have considerable development prospects in endoscopy and histopathology due to their excellent image analysis capabilities.In recent years,the application of AI diagnostic models has become more and more widespread,but at the same time,there are still some limitations about algorithms,databases and their applications that cannot be ignored.This review mainly focused on the application of AI in IBD diagnosis from the aspect of image recognition,to provide a reference for IBD diagnosis towards precision medicine.
