18F Fluoride

Background:Bone formation in spondyloarthritis (SpA) is presumably related to local enthesitis/peri-articular inflammation and ultimately may lead to functional limitation (1,2). X-rays only allow long-term monitoring of bone formation (≥2 years) (3). Imaging techniques that can visualize bone formation at an early stage would therefore be valuable. Positron Emission Tomography (PET) using [18F]Fluoride can visualize and quantify (early changes in) bone formation at molecular level (4).Objectives:To investigate the feasibility of [18F]Fluoride to assess new bone formation at axial and peripheral enthesial sites in SpA patients.Methods:Thus far, 5 of the total of 15 patients with clinically active ankylosing spondylitis (AS) (according to modified New York criteria and BASDAI ≥4) and 8 of the 25 patients with active psoriatic arthritis (PsA) (according to CASPAR criteria and ≥1 clinically active enthesitis) were included. Of each patient, a whole body [18F]Fluoride PET-CT scan was performed. All scans were visually judged and scored dichotomously by one reader (blinded for clinical data) for PET-positive lesions in the spine, peripheral enthesis sites and joints. Low dose CT was used for anatomical reference.Results:The study is ongoing, with whole body [18F]Fluoride PET-CT scans available in five AS patients and eight PsA patients. In 4/5 AS scans, at least (≥1) PET positive lesions were found in the cervical, thoracic and/or lumbar vertebrae. These were mainly found in anterior corners of vertebrae and bridging syndesmophytes (Fig. 1A). In all eight PsA patients, at least 1 PET positive lesion was visualized, projected either at the site of a tendon attachment (fascia plantaris, achilles- and patella tendon (Fig 1B)) or peri-articularly (in the ankle or wrist).Fig 1.[18F]Fluoride uptake in the cervical, thoracic and lumbar spine in a clinically active AS patient (A) and in the patella tendon of the right knee in a clinically active PsA patient (B)Conclusion:[18F]Fluoride PET uptake, reflecting new bone formation, can be visualized at heterogeneously distributed enthesis and (peri-)articular sites in AS- and PsA patients. The technique therefore is sensitive to visualize new bone formation and may reflect local disease activity. Additional scans will be collected and analyzed quantitatively, also after anti-TNF or Secukinumab treatment, to further investigate the applicability of [18F]Fluoride PET for monitoring of therapeutic effects on bone formation in SpA.References: :[1]Maksymowych WP, Mallon C, Morrow S, Shojania K, Olszynski WP, Wong RL, et al.
