Fig. 2From: 18F-NaF PET/CT imaging of bone formation induced by bioactive glass S53P4 after mastoid obliterationAxial 18F-FDG-PET/CT revealing increased uptake of the obliterated area, without uptake in the centrally located fluid area. The FDG uptake was considered too low for infection, but more likely a visualization of metabolic activity in the obliterated mastoid and middle ear cavityBack to article page
