Objective To explore magnetic resonance imaging(MRI)characteristics of brain glioma(BG)and their relationship with prognosis.Methods A retrospective analysis was performed on the imaging data of 102 patients with BG who underwent preop-erative MRI examination in the hospital between January 2020 and December 2021.All were followed up for 18 months to record MRI characteristics,including tumor size,sites,margin,space-occupying effect and tumor enhancement characteristics.The correlation be-tween MRI signs and prognosis of patients was explored.Results In the 102 patients after 18 months of follow-up,overall survival rate was 41.18％(42/102).Among them,there were 42 cases in survival group and 60 cases in death group.There were no significant difference in tumor sites or fuzzy tumor boundary between the two groups(P＞0.05).The proportions of tumor diameter＞6cm,obvious space-occupying effect,obvious peritumoral edema,cystic lesions,hemorrhage,necrotic lesions and obvious uneven enhancement of lesions in death group were higher than those in survival group(P＜0.05).Conclusion The MRI features of BG patients with tumor di-ameter,space occupying effect,peritumoral edema,cystic change,hemorrhage,necrotic lesions,and significant uneven enhancement of lesions are significantly correlated with the prognosis of patients,and can be used to evaluate the prognosis clinically.
