Each lesion is represented as a diamond for lung lesions and a square for involved lymph nodes. Thopt, the optimal threshold to be applied for delineation is expressed as a linear regression such as Thopt = A.[ln (1/SUVmax)] + B of the maximum standard uptake value (SUVmax). The expression of Thopt for lung lesions and lymph nodes are presented with their respective coefficient of determination R2
