From: Use of 18F-sodium fluoride bone PET for disability evaluation in ankle trauma: a pilot study
Radiologic and 18F-sodium fluoride (18F-NaF) positron emission tomography-computed tomography (PET/CT) images of a 53-year-old male patient who had a right calcaneus fracture and underwent operation with plate-screw fixation. a-d Initial images of plain radiographs and computed tomography (CT); a calcaneal anterior-posterior view, b calcaneal CT axial view, c ankle lateral view, d calcaneal CT lateral view. Note that the fracture did not involve the talocrural (tibiotalar) joint. e, f Plain radiographs performed at 9 months after injury presents plate-screw fixation, but does not give any information about talocrural joint pathology and the degree of ankylosis in the ankle. g-i 18F-NaF PET/CT shows hot uptake around the talocrural joint away from the initial fracture and plate-screw fixation area
