Structural association between heterotopia and cortical lesions visualized with 7T MRI in patients with focal epilepsy
PurposeTo analyse structural characteristics of malformations of cortical development (MCD) at 7T and 3T MRI.MethodsTwenty-five patients were examined with a 7T MRI-scanner in addition to 3T examinations performed for epilepsy evaluation. 7T sequences included a 3D-T1-weighted (T1w) MPRAGE, 3D-T2w FLAIR, and heavily T2w axial and coronal high-resolution (0.5×0.5×0.75-1.0 mm3) 2D-TSE sequences.
