Patient scans in the old and new dose regimens. Coronal and transverse slices of a whole-body FDG-PET scan for (A) a patient of 70 kg (dose = 149 MBq) and (B) a patient of 95 kg (dose = 217 MBq), using the old dose regimen, and for (C) a patient of 70 kg (dose = 138 MBq) and (D) a patient of 95 kg (dose = 257 MBq), using a quadratic relation between body mass and FDG dose. Using the old relation between body mass and dose, the dose would have been (C) 149 and (D) 217 MBq, respectively. All four scans were performed on the Biograph TruePoint. The location of the transverse slice is indicated on the coronal view.
