Abstract
Objective To evaluate the value of MRI and 1H-MRSI in the lacalization diagnosis ( LD)of temporal lobe epilepsy (TLE). Methods 15 selected patients with TLE verified by clinical manifestations and diagnosis of EEG and 15 healthy volunteers were studied. One-time conventional MRI and bilateral hippocampus 1H-MRSI inspection. Results 5 of these patients showed unilateral hippocampus sclerosis. ' H-MRSI of hippocampal was positive in 8 cases, 3 cases showing bilateral abnormalities , combination of the two methods can accurate positioning of locases. Conclusion 1H-MRS was more sensitive than MRI in lateralizing seizure origin, and bilateral lesions can be foung but MRI was more specific than 1H-MRS. Combination of MRS with MRI can improve the accuracy ratio of the localization diagnosis.关键词
