Several PET-derived parameters were calculated (SUV and TBRmax), and tumor volumes of TSPO-positive lesions were measured by applying various SUV-based thresholds (SUVBG × 1.6, SUVBG × 1.8, SUVBG × 2.0), thus generating corresponding volumes V1.6, V1.8, and V2.0. This evidence concerns the gene TSPO and neoplasm.
