W: Body weight (kg)
A: Injected activity (MBq)
SUV: SUV (g/ml)

Lecture brief

Historical brief

MIRD schema, in-vivo decay, uptake fractions and PET coincidence turned unsealed sources into organ dose. The sheets compute activity, residence and well-counter geometry. This sheet (NMD-14 — Standardised uptake value) is the form associated with SUV. Working symbols: $C$ , $W$ , $A$ $\rightarrow$ $SUV$ . Units: C in kBq/ml, W in kg, A in MBq → g/ml. SUV is 1 if the tracer spreads uniformly in 1 g/ml tissue.

in Nuclear medicine via

\mathrm{SUV}=C\,W/A

SUV = C W / A. Concentration times body weight over injected activity. Use it when a real nuclear medicine question must be answered in SI before a code check.

Live realistic example

In symbols

Live case. Given

C = 12.000\,\mathrm{kBq/ml}

W = 70.000\,\mathrm{kg}

A = 370.000\,\mathrm{MBq}

, the governing relation

\mathrm{SUV}=C\,W/A

yields

SUV = 2.27\,\mathrm{g/ml}

. A VOI concentration normalised to the injection. Move a slider: the numbers are this situation, not a canned story.
