The SNR of different acquisition durations images with Gaussian and DL image filter. The SNR of the liver (A) and mediastinal blood pool (B, measured at descending aorta) of the DL image filter image with different acquisition durations is higher than that of the Gaussian filter image (P < 0.01). C and D show that the SNR improves steadily as the acquisition time increases, for both Gaussian and DL image filter images. There is no statistical difference in the SNR of the liver (E) and mediastinal blood pool (F) between the 20- and 30-s DL image filter image and the 300-s Gaussian filter image (P > 0.05)
