Target Volume Determination 2015

Respiration correlated FDG-PET/CT

Consequences for GTV delineation: I Stage I / SABR: ― Delineation on CT of all (8) phases of the respiratory cycle ― ITV generated on 3D-FDG-PET is NO surrogate!! ― Automatically segmented 4D-FDG-PET may provide additional information I Advanced stage: ― Delineation of target volume on CT of 3 respiratory phases – i.e., 0%/50%/100% exspiration ― FDG-PET provides additional information, e.g. Atelectasis.
