[Abstract] Cognitive function impairment is the most common clinical manifestation of radiation-induced brain injury. The diagnosis is mainly based on clinical features and neuropsychological scales. The process of cognitive function impairment after radiotherapy is related to the pathological changes. This article reviews the latest progress in the pathological processes related to cognitive function impairment after radiotherapy and the application of MRI. It summarizes the early imaging manifestations and corresponding pathological changes of radiation-induced brain injury in different sequences, and the application of artificial intelligence and radiomics based on MRI in predicting patients with cognitive function impairment after radiotherapy. Based on this, the research direction of artificial intelligence and radiomics combined with multi-sequence MRI for early diagnosis of cognitive function impairment after radiotherapy is proposed, which is helpful for early and accurate identification of patients with cognitive function impairment after radiotherapy and early intervention to improve the quality of life of patients.
