It can automatically makea quantitative assessment of complex medical images and help doctors to makemore accurate diagnoses. In recent years, AI based on ultrasound has been shownto be very helpful in diffuse liver diseases and focal liver lesions, such asanalyzing the severity of nonalcoholic fatty liver and the stage of liver fibrosis,identifying benign and malignant liver lesions, predicting the microvascularinvasion of hepatocellular carcinoma, curative transarterial chemoembolizationeffect, and prognoses after thermal ablation. Moreover, AI based on endoscopicultrasonography has been applied in some gastrointestinal diseases, such asdistinguishing gastric mesenchymal tumors, detection of pancreatic cancer andintraductal papillary mucinous neoplasms, and predicting the preoperative tumordeposits in rectal cancer. This review focused on the basic technical knowledgeabout AI and the clinical application of AI in ultrasound of liver and gastroenterologydiseases. Lastly, we discuss the challenges and future perspectives of AI.展开更多

We investigated the utility of tracing as a memory storage method. Young and elderly participants learned a figure from the Rey-Osterrieth complex figure test by copying or tracing its outline. They were asked to reproduce the figure after 3 min and 3 days. Although the copying group performed better than the tracing group in immediate recall after 3 min, the performance of the tracing and copying groups after 3 days was similar. Among younger participants, the tracing group achieved higher scores than the copying group after 3 days;however, the difference was not statistically significant. Copying as a learning strategy has a substantial temporal gradient of memory loss;tracing may be more appropriate for improving long-term memory. This result could have considerable practical usefulness, e.g., among professionals who provide memory training for the elderly. Tracing, which uses visuomotor memory, is acquired earlier than transcription. Tracing may be effective for rehabilitation because it is a developmentally appropriate approach to early instruction.展开更多
