Response criteria using positron emission tomography for assessment of therapy response
Expansion
PET Response Criteria in Solid Tumours
Purpose
Measures metabolic response using standardised uptake ratio based on lean body mass
Clinical Context
PERCIST: Complete metabolic response if standardised uptake ratio peak less than or equal to mean liver standardised uptake ratio plus 1.5 times standard deviation; partial response if greater than or equal to 30 percent standardised uptake ratio reduction.
Related Terms

- Positron emission tomography imaging
Key Points
- PERCIST uses change in standardised uptake ratio peak; complete response if standardised uptake ratio less than or equal to target liver plus 1.5 times standard deviation
