Fig. 1From: Bottom-of-sulcus dysplasia: the role of 18F-FDG PET in identifying a focal surgically remedial epileptic lesionAppearance of BOSD on PET and MRI. (a) Coregistered PET and MRI data is shown for one patient who exhibited BOSD MRI hallmarks, as well as focal hypometabolism on 18F-FDG-PET. The area of focal hypometabolism is shown in the dashed box. The area of PET hypometabolism is shown in an inset area in (b) using a jet colour scheme. The FLAIR image (c) shows T2 hyperintensity of the BOSD, while this appears as a hypointensity on T1 (d)Back to article page
