    FIGURE 2.

    Comparison of overall reduction of emitted radiation from voiding after decay correction of categorized 18F-FDG patients with corresponding P values. P values indicate no statistical significance between different patient categories regarding effect of decay-corrected void. Youth group has only 2 patients, therefore, P value of this group was not calculated.

    Comparison of overall reduction of emitted radiation from voiding after decay correction of categorized 18F-NaF patients with corresponding P values. P values demonstrate that there was no statistical significance between different categories regarding effect of decay-corrected void. Youth group has only 2 patients, therefore, P value of this group was not calculated.
