Article Figures & Data

Figures

  • FIGURE 1.
    FIGURE 1.

    Anterior perfusion images of head, neck, and mediastinum show focus of mildly increased tracer flow in region of oral cavity (arrows).

  • FIGURE 2.
    FIGURE 2.

    Planar images acquired 20 min after tracer injection show 2 distinct foci of uptake in oral cavity and submental region (arrows in oblique views, B and C). These foci were superimposed on anterior image (arrow in A). Anterior view acquired with further neck extension (D) shows 2 distinct foci of uptake (upper and lower dashed arrows represent markers placed at chin and suprasternal notch, respectively). Thyroid is not visualized at its normal location in neck. Tracer distribution in thoracic region is suggestive of uptake in both breasts (arrowheads in D).

  • FIGURE 3.
    FIGURE 3.

    Sagittal and transaxial SPECT (A and B, respectively) and SPECT/CT (C and D, respectively) images. Increased uptake is seen in soft-tissue density at base of tongue at midline (arrow 1), and smaller ill-defined focus of increased uptake is seen in floor of mouth in suprahyoid–submental region (arrow 2).
