(B)MRI findings of patients with confirmed FCD and T2* signal changes. 7T T2 (A-D), T2* (E-H), and T2* minimum intensity projection (I-L) coronal reconstructions. Lesions are depicted in detail in (B), (D), (F), (H), (J) and (L). Patient III; mild malformation of cortical development type 2 (A, B, E, F, I, J). On T2 (A, B), blurring and subcortical hyperintensity represent developmental malformation. T2* (E, F) shows a wide Sylvian fissure but no clearly appreciable vascular changes. On T2* minimum intensity projection (I, J), there appears to be an increase in vascular signal in the superior temporal pole. Patient IV (C, D, G, H, K, L); FCD ILAE type IIb. On T2 (C, D), there is a notable large central parasagittal extracerebral space containing a large vein, but without evident dysplastic characteristics, however, on T2* (G, H), the large vein and smaller vasculature that drains from the dysplastic cortex (as confirmed by histological examination) is observed. (K, L) Image enhancement on T2* minimum intensity projection.
