A: T1-weighted images of the region of PVNH (yellow arrow). Black arrows denote “bridges” connecting the PVNH to outlying cortices. B: T2-weighted images and MR spectroscopy (chemical shift imaging) of a volume mostly inside the PVNH (yellow arrows) illustrating N-acetylaspartate (NAA), choline (Cho), and creatine (Cr) peaks characteristic of cortex. C: Three-dimensional reconstruction of the PVNH (yellow) amid a volumetric model of the ventricles (magenta) with diffusion-weighted tracts (green) connected to the PVNH seed region (1.6-mm3 resolution). s. = sulcus; x,y,z = Talairach coordinates.
