FIGURE 1. Periodontal Inflammation and Bone Marrow Activity.
(A) Representative periodontal (top) and bone marrow (bottom) fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) images. Yellow arrows show locations of increased activity. âTâ indicates activity in the tongue. (B) The relationship between periodontal inflammation and bone marrow activity (r = 0.56, p < 0.001), as quantified using 18F-FDG-PET/CT. TBR = target to background ratio.
