## Conventional Indices

CONV_SUVmin reflects the minimum Standardized Uptake Value (SUV) in the Volume of Interest.

CONV\_SUVmin=\min_{i}SUV_i

CONV_SUVmean reflects the average SUV in the Volume of Interest.

CONV\_SUVmean=\frac{1}{N}\sum_{i}SUV_i

CONV_SUVmax reflects the maximum SUV in the Volume of Interest.

CONV\_SUVmax=\max_{i}SUV_i

CONV_SUVpeak reflects the mean SUV in a sphere with a volume of ~0.5 or ~1 mL and located so that the average value in the VOI is maximum.

CONV_TLG (mL) is the Total Lesion Glycolysis defined as the product of $$SUVmean$$ by $$Volume$$ in mL. [LARSON 1999]

CONV\_SUVmean=V \cdot \frac{1}{N}\sum_{i}SUV_i
