Prevalence of Clinically Significant Extraosseous Findings on Unenhanced CT Portions of ¹⁸F-Fluoride PET/CT Bone Scans

Figure 1

CT image from a 48-year-old male patient diagnosed with hepatocellular carcinoma. The followup unenhanced CT of ¹⁸F-fluoride PET/CT, in the lung window, revealed numerous tiny pulmonary nodules in the bilateral lungs (arrows). The largest nodule was 0.6 cm in size and none of these nodules were visualized by concurrent chest X-ray.
