چکیده مقاله:

Background and purpose: In visual assessment of mesial temporal lobe sclerosis MRI study, there are a few pitfalls , sometimes difference between signal of two hippocampus is not possible and sometimes bilateral abnormal signal .Intensity of hippocampus effects our decision making .Our goal is to compare visual assessment and T2 relaxometry for detecting hippocampal sclerosis. Materials and methods: 50 patient with mesial temporal lobe sclerosis diagnosed by clinic and EEG were analyzed by neuroradiology and then T2 relaxometry study by 16 multiecho images was performed for comparison. Result: Visual analysis categorized 65% of patient as hippocampus sclerosis and about 35% as normal but T2 relaxometry detected about 80% of patient with visually detected HS and about 30% with visually normal MRI findings, considering together, visual assessment plus T2 relaxometry can detected about 75% of hippocampus sclerosis. Conclusion: Use of T2 relaxometry, can increase detection of hippocampus sclerosis in about 30% of patient with normal visual MRI findings .
