FIGURE 2.  Three-compartmental 4k bone kinetic model described by Hawkins et al. (7) to analyze 18F-fluoride PET bone studies. See text for description of rate constants. RBC = red blood cells; ECF = extracellular fluid.

FIGURE 3.  Representative study showing image-derived arterial plasma input function (continuous line) and vertebral ROI time–activity curve ({blacktriangleup}). Vertebral values have been multiplied by 4 for easier comparison with input function. Decay corrections have been applied.

FIGURE 5.  Box plot showing differences in repeated measurements for Ki-4k, Ki-3k, and Ki-PAT (A) and for SUVmean (B). Boxes represent values between 25th and 75th percentiles, horizontal bars inside boxes indicate median, vertical bars above and below boxes represent 10th and 90th percentiles, outliers greater than 1.5x interquartile range are presented by circles, and extreme values greater than 3x interquartile range are indicated by asterisk.
