Fig. 8 — NaF-PET maximum intensity projection (MIP) of the upper body (A) and lower body (B) of a patient with rheumatoid arthritis. Focal areas of high bone formation in the joints were segmented using an adaptive thresholding algorithm (ROVER software, ABX GmbH, Radeberg, Germany). Metabolically active volume (MAV), maximum standardized uptake value (SUV_max), mean SUV (SUV_mean), partial volume-corrected SUV_mean (pvcSUV_mean), total calcium metabolism (TCM), and partial volume-corrected TCM (pvcTCM) were calculated and summed for each segmented region. The overall pvcTCM for this patient was 1898.8.
