The primary outcome is the clinical response to lithium treatment at 1 year follow-up, assessed using a validated questionnaire.

The hospital is running a completely new project dedicated to applying MRI technology in the field of psychiatry, and Professor Dousset will manage the project. However, this is an entirely new domain for the radiologists and technicians in the hospital. Therefore, Professor Dousset attended the ISMRM-endorsed Workshop on MR for Psychiatry in Chengdu to gain insight into the latest advancements in psychoradiology and hoped to apply valuable experience to their project. Following the conference, the <i>Psychoradiology</i> journal interviewed Professor Dousset. In the interview, Professor Dousset was enthusiastic about merging radiology and psychiatry teams and regarded the term \"psychoradiology\" as a bridge to unite these fields. Despite the challenges of distinguishing normal from abnormal brains in psychiatric disorders, he was optimistic about the future of psychoradiology and its clinical applications.
