Figure 1. Transaxial (left), coronal (middle), and sagittal (right) 18F-FDG PET scans obtained in an 11-year-old boy with lymphoma demonstrate an inverted V-shaped area of anterior mediastinal uptake on the transaxial view with a maximum standardized uptake value (SUV) of 3.0. Given the morphologic features, this finding is typical of normal thymic uptake.
