Article Figures & Data

Figures

  • FIGURE 1.
    FIGURE 1.

    (A) Chest radiographs without pathologic findings. (B–G) Subsequent axial CT (B and C), PET (D and E), and PET/CT (F and G) images showing pleural consolidative areas that are 18F-FDG–positive (SUVmax, 3.6). (H) Maximum-intensity projection showing hypermetabolic inguinal lesions.

  • FIGURE 2.
    FIGURE 2.

    (A) Maximum-intensity projection showing increased 18F-FDG uptake at right epiglottis and cervical nodes. (B–G) Axial CT (B and C), PET/CT (D and E), and PET (F and G) images showing interstitial pneumonia with 18F-FDG–avid GGOs (SUVmax, 2).

  • FIGURE 3.
    FIGURE 3.

    (A and B) High-resolution thoracic CT scan with no sign of pneumonia. (C–H) PET/CT images obtained 2 wk later, showing GGOs and consolidative areas in right inferior lobe on CT (C and D), PET/CT (E and F), and PET (G and H), with SUVmax of 7.7. (I) Maximum-intensity projection confirming pulmonary uptake.

  • FIGURE 4.
    FIGURE 4.

    (A and B) High-resolution thoracic CT with no sign of pneumonia. (C–H) PET/CT performed 1 wk later, showing bilateral pneumonia with GGOs on CT (C and D), PET (E and F), and PET/CT (G and H) images, with SUVmax of 5. (I) Maximum-intensity projection showing 18F-FDG–positive axillary nodal lesion.

  • FIGURE 5.
    FIGURE 5.

    (A–F) Axial CT (A and B), PET/CT (C and D), and PET (E and F) images showing increased radiotracer uptake corresponding to interstitial lung alterations (SUVmax, 5.3). (G) Maximum-intensity projection showing entire body.

  • FIGURE 6.
    FIGURE 6.

    (A–I) Axial CT (A and B), PET/CT (C and D), and PET (E and F) images showing significant pneumonia with GGOs, especially in left lung (SUVmax, 6.9), and 18F-FDG–avid mediastinal nodes (G–I) (J). Maximum-intensity projection confirming lung and nodal alterations.

  • FIGURE 7.
    FIGURE 7.

    (A and B) Whole-body anterior (A) and posterior (B) scintigraphic images after radioiodine treatment showing focal uptake in neck consistent with thyroid remnant. (C and D) Several axial CT (C) and SPECT/CT (D) fused slices characterized by various bilateral GGOs without radioiodine uptake.
