Voxel intensity histograms at a baseline (BL) and b 8 weeks (8W) with kernel fits of a metastasis in a patient with PD on [18F]fluoride PET/CT. As well as an increase in intensity of voxels (SUVmax rose from 32.7 to 38.0 and SUVmean from 12.8–15.3), the histogram becomes less peaked (kurtosis decreased from 5.6 to 3.1).
