Brain CT (axial) the same day of onset, showing high density in the left putamen (arrow); b. Brain CT (axial) 24Â days after onset, showing slight high-density in the same area (arrow), but the density decreased compared with the initial CT; c. MRI (axial) of the head 62Â days after onset, demonstrating hyperintensity on T1-weighted images in the putamen (arrow); d. The FDG-PET scan (axial) 55Â days after onset, revealing hypo-perfusion in the left side of the basal ganglion.Back to article page
