Figure 4From: Dental artifacts in the head and neck region: implications for Dixon-based attenuation correction in PET/MR Representative patients from Group INNER (A-D) and Group OUTER (E-H). Note the recovery of tracer activity in the proximity of the artifact when comparing (F) to (G). Panels (D,H) show the corresponding relative PET difference images for (A,B) in relation to (B) and (E-F) to (F), respectively.Back to article page
