Table 1.
SUV parameter | Definition | AUC in the ROC curve | p-value** |
---|---|---|---|
SUVmax | decay-corrected activity of tissue volume/injected activity per body mass | 0.84 | Not applicable |
SUVbmi | (SUVmax/body weight) × BMI | 0.86 | 0.15 |
SUVbsa | (SUVmax/body weight) × BSA | 0.86 | 0.43 |
SUVcer | SUVmax/SUVcerebellum | 0.87 | 0.32 |
SUVgluc | SUVmax × blood glucose level/100 | 0.90* | 0.03*** |
SUVgluc has the highest AUC among semiquantitative parameters.
p-value is in comparison to SUVmax.
SUVgluc is the only SUV parameter which significantly improves diagnostic accuracy of SUVmax in differentiating benign vs. malignant lung nodules (P = 0.03).
