Method | Semi-automated measurements | Visual assessment | |||
|---|---|---|---|---|---|
MTV2.5 | MTV41 | eMTV | MTVVAS | Prognosis | |
Description | Metabolic tumor volume delineation > SUV 2.5 | Metabolic tumor volume delineation > 41% of SUVmax | Metabolic tumor volume assessed visually | Degree of metabolic tumor volume assessed on VAS scale | Prognosis assessed visually based on volume, heterogeneity, involvement of extra-nodal organs |
Parameter | Continous (ml) | Continous (ml) | Continous (ml) | Continous (1–9) | Dichotomous (poor/favorable) |
