摘　　要：Major depressive disorder(MDD)with suicidal ideation or behaviour(MDSI)is associated with an increased risk of future suicide.The timely identification of suicide risk in patients with MDD and the subsequent implementation of interventions are crucially important to reduce their suffering and save lives.However,the early diagnosis of MDSI remains challenging across the world,as no objective diagnostic method is currently available.In China,the challenge is greater due to the social stigma associated with mental health problems,leading many patients to avoid reporting their suicidal ideation.Additionally,the neural mechanisms underlying MDSl are stll unclear,which may hamper the development of effective interventions.We thus conducted this narrative review to summarise the existing neuroimaging studies of MDSI in Chinese patients,including those involving structural magnetic resonance imaging(MRI),functional MRl,neuronal electrophysiological source imaging of the brain dynamics with electroencephalography and magnetoencephalography.By synthesising the current research efforts in neuroimaging studies of Chinese patients with MDSl,we identified potential objective neuroimaging biomarkers,which may aid in the early identification of patients with MDSI who are at high suicide-related risk.Our findings also offer insights into the complex neural mechanisms underlying MDSI and suggest promising therapeutic targets.Furthermore,we propose future directions to discover novel imaging signatures,improve patient care,as well as help psychiatrists and clinical investigators plan their future research.
