Figure 2: A 5-year-old male with Langerhans cell histiocytosis underwent 18F-fluorodeoxyglucose positron emission tomography/computed tomography for evaluation of disease activity and extent. Positron emission tomography maximum intensity projection image (a) shows pixilation due to extravasation of radiotracer in the right elbow region. Maximum intensity projection image (d) obtained post correction by reducing radial field of view shows resolution of the artifact. The transaxial positron emission tomography image quality at the level of brain and abdomen was not affected before (b and c) and after correction (e and f) of positron emission tomography data
