Patient Size-Dependent Dosimetry Methodology Applied to F-FDG Using New ICRP Mesh Phantoms.

Despite the known influence of anatomic variability on internal dosimetry, dosimetry for F-FDG and other diagnostic radiopharmaceuticals is routinely derived using reference phantoms, which embody population-averaged morphometry for a given age and sex. Moreover, phantom format affects dosimetry estimates to varying extent. Here, we applied newly developed mesh format reference phantoms and a patient-dependent phantom library to assess the impact of height, weight, and body contour variation on dosimetry of F-FDG.
