Quantitative analysis of PET images

Tracer uptake is frequently quantified by the Standardized uptake value (SUV)

w A C SUV =

with C: tumor/voxel activity concentration [Bq/ml] A : injected activity [Bq] w : body weight [g]

!!! SUV=1 means that the tracer is equally distributed in the whole body ESTRO Teaching Course Advanced Imaging: PET – Reconstruction, Contouring 30
