Zusammenfassung
Purpose: Curative neurosurgical treatment options for patients with focal epilepsies demand accurate anatomical identification of the epileptogenic lesion by MR imaging. The most typical lesion in temporal epilepsies is a hippocampal sclerosis. Therefore, the aim of this study is to implement and test an adopted imaging protocol at 7 Tesla in patients with known hippocampal sclerosis focussed on maximum spatial resolution and scan time. Material and methods: Seven patients with hippocampal sclerosis were investigated with T1-, T2-, T2*- and FLAIR-weighted sequences at 7 Tesla (Magnetom 7T, Siemens, Erlangen; 8-c…
