The same patient. MIP PET images (A), axial PET images of colon cancer (B), and axial PET images of liver metastases (C) with DL image filter with different acquisition durations (10, 20, 30, 60, and 120 s). With DL image filter, the noise of the image is significantly reduced and the image quality is significantly improved. With the 300-s Gaussian filter image as a standard image reference, sub-centimetre liver metastases (red arrow) become blurred on DL image filter image
