Standardized uptake value, abbreviated SUV, is a semi-quantitative measure in PET scans.

SUV={\frac {c(t)}{injected\ dose(t_{0})\quad /\quad body\ weight}}

The SUV of fluorine-18 fluorodeoxyglucose of the primary tumour is a predictor of lymph node metastases in a multivariate analysis.^[1]
- Cut-off: 9.3.
  - Sensitivity ~75%.
  - Specificity ~54%.
