Figure 5. MRI of ICH and ICH-based device. (A, from left to right) Photograph of ICH at the time of implantation, axial and coronal view of the ICH subsequently after implantation, and visualized ICH volume; (B, from left to right) Photograph, axial and coronal view, and visualized ICH volume at 4 weeks after implantation; (C, from left to right) PVDF-HFP (dotted) conformally intact to brain tissue and ICH (dotted) visible without artifact in coronal, axial, and sagittal views as an electrode array device. MRI: magnetic resonance imaging; ICH: injectable conductive hydrogel; PVDF-HFP: poly(vinylidene fluoride-co-hexafluoropropylene).
