(A) Example of non-responder patient classified by SULTAN. First PET showed right hilar hypermetabolism, and second PET performed in therapeutic monitoring (exam 2) showed a progression with persistence of right hilar hypermetabolism and the appearance of a hypermetabolic right lung uptake. The evolution was classified as non-responder. Factorial image obtained by SULTAN was superimposed on the CT-scan 1 (B). Associated curves (C) represented the growing trend (red) or stable (blue) voxels. The developments described by factor analysis were similar to those of SUVmax (D) with a stability of hilar fixation and the appearance of a right pulmonary uptake.
