[18F]-FDG PET images of a 60-y/o male (362 MBq, BMI = 28) with colorectal cancer. Images show lewsions in the liver and right lower lung that are affected by motion-induced blurring. Left: without motion compensation, middle: with amplitude motion compensation that utilizes 35% of the acquired data resulting in noisy images but reduced motion artifact, and right: with amplitude motion compensation that utilizes all the acquired data resulting in lower image noise and motion artifact
