Deauville score
Pronunciation: doe-VILL
Five-point scale for interpreting PET scan response in lymphoma patients. Standard imaging assessment tool.
Full Definition
The Deauville score is a standardized five-point scale used to interpret fluorodeoxyglucose positron emission tomography (FDG-PET) scans in lymphoma patients, particularly for assessing treatment response. Developed at a consensus meeting in Deauville, France, the scoring system compares lymphoma uptake to normal tissues: score 1 indicates no uptake above background, score 2 shows uptake ≤ mediastinal blood pool, score 3 demonstrates uptake > mediastinal but ≤ liver, score 4 reveals uptake moderately higher than liver, and score 5 indicates markedly increased uptake or new lesions. Scores 1-3 generally indicate good response, while scores 4-5 suggest inadequate response requiring treatment modification.
Usage
Usage note: Named after the French city. Always capitalize. Use Arabic numerals for scores (1-5).
