PET Standardised Uptake Value (SUV)

Calculate the SUV for a PET scan from injected activity, patient weight and tissue concentration, with decay correction, free online.

Injected activity (MBq)

Patient weight (kg)

Tissue concentration (kBq/mL)

Minutes between injection and scan

Isotope half-life (min; F-18 = 109.77)

À propos de cette calculatrice

SUVbw = tissue activity concentration (kBq/mL) ÷ (injected activity (kBq) ÷ body weight (g)), where the injected dose is decay-corrected to scan time. For F-18 the half-life is 109.77 minutes. SUV above about 2.5 in a lesion is often considered suspicious, but interpretation requires a radiologist.
