Comparison of the SNR among different percentages of ASIR-V and 40% ASIR images. The graph showed that the SNR values of fat, muscle and aorta on all ASIR-V series significantly increased along with the increasing ASIR-V percentage in comparison with the images reconstructed using 40% ASIR. ASIR, adaptive statistical iterative reconstruction; ASIR-V, adaptive statistical iterative reconstruction V; SNR, signal-to-noise ratio.
