The invention belongs to the technical field of artificial intelligence, and discloses an LI-RADS diagnostic report generation system and method based on artificial intelligence. The LI-RADS diagnostic report generation system comprises an information acquisition module, an image acquisition module, a key frame acquisition module, an image recognition module, an image marking module, a processing module and a report generation module. According to the LI-RADS diagnostic report generation method, the key frame image is recognized through the target detection model based on artificial intelligence, the size and the feature of the focus are obtained and then matched with the diagnosis table, the type of the focus can be obtained and presented on the diagnosis report, misdiagnosis caused by subjective factors of people is avoided, the diagnosis speed is increased, and the diagnosis accuracy is improved.
