Article Figures & Data

Figures

  • FIGURE 1.
    FIGURE 1.

    Partial extravasation (arrow) of 18F-FDG in patient in whom reconstructed study excluded injection site from field of view.

  • FIGURE 2.
    FIGURE 2.

    Time–activity curves for injection site (black) and control arm (red) showing rapid peak of injection bolus followed by static residual activity in injection arm, suggestive of extravasation (A), and normalization to control arm, suggestive of no extravasation (B).

  • FIGURE 3.
    FIGURE 3.

    Whole-body (truncated at hips) imaging at 60 min after intravenous administration of 18F-FDG. (A) PET/CT image of low count and poor quality. (B) PET image showing skin contamination of radiopharmaceutical (arrows).

  • FIGURE 4.
    FIGURE 4.

    Repeated 18F-FDG PET/CT scan (left) demonstrating superior counts and quality compared with original scan (right), which had count loss associated with leaked activity.
