We are always facing global FDG uptake in pediatric patients, is there a solution for this issue?

“Global as in total body vertex to toes? The reason for this is that pediatric malignant disease can often occur distally in children, i.e. below elbows and knees. The time to add on the few bed positions can sometimes make a difference in staging. However, we do routinely decrease our time for bed postion in the head and extremities from torso. We would routinely decrease from 2 min for torso to 1 min for head and extemities without prior knowledge of disease in these areas.

Recently we have had an IAEA publication that does state that in PEDIATRIC LYMPHOMA the incidence of disease that may upstage the patient is low enough to restrict to ‘eyes to thighs” imaging but I caution this is validated currently only for lymphoma.”
