Objective Analysing the value of magnetic resonance diffusion tensor imaging(DTI)in paediatric temporal lobe epilepsy.Methods 68 children with temporal lobe epilepsy who received medical treatment in Qinghai Women and Children's Hospital from January 2022 to December 2023(set as the observation group)and 68 children without epilepsy who underwent physical examination in Qinghai Province Women and Children's Hospital during the same period(set as the control group)were selected as the study objects,and DTI examination was performed.The anisotropy fraction(FA)and average dispersion coefficient(MD)of hippocampal and temporal lobe were compared between the two groups,and the differences of FA and MD of hippocampal sclerosis(HS)and non-HS type temporal lobe epilepsy in patients,healthy hippocampus and temporal lobe were analyzed.Results MD on the affected side of hippocampus and temporal white matter in observation group was higher than that in the control group,FA was lower than that in the control group,the difference is statistically significant(P＜0.05).The white matter MD of hippocampal and temporal lobe in children with HS type temporal lobe epilepsy was higher than that on healthy side,and healthy side and affected side in children with non-HS type temporal lobe epilepsy,the difference is statistically significant(P＜0.05),but there was no statistical significance in the difference between the white matter MD of hippocampus and temporal lobe in children with HS type temporal lobe epilepsy and healthy side(P＞0.05).The hippocampal FA on the affected side of children with HS type temporal lobe epilepsy was lower than that on the healthy side,and the healthy side and the affected side of children without HS type temporal lobe epilepsy,the difference is statistically significant(P＜0.05),while there was no statistical significance in the comparison of bilateral temporal lobe white matter FA between children with HS type and non-HS type temporal lobe epilepsy(P＞0.05).Conclusion DTI can effectively assist in determining the location of temporal lobe epilepsy in children.
