North American consensus MBq/kg ballpark.
When to use
Bedside ballpark for bone, DMSA, MAG3/DTPA, thyroid Tc, MIBG, FDG. Institutional protocols prevail.
How it works
A = (MBq/kg)×weight with published clamps; or A_adult×(W/70) then clamp.
Key points
- North American consensus MBq/kg ballpark.
- Compare EANM Paediatric Dosage Card.
- Estimate only — not a prescription.
