Fig. 3From: KRAS mutation effects on the 2-[18F]FDG PET uptake of colorectal adenocarcinoma metastases in the liverRecovery coefficients (RC) used for applying PVE correction to the tracer uptake of each lesion. The symbols represent the measured RC for each NEMA NU-2 image quality phantom sphere. The final recovery coefficients used for PVE correction (lines) are obtained by applying a correction for the cold walls of the phantom spheres obtained by using a RC model [42] to compute the recovery coefficient ratio for spheres with and without wallsBack to article page
