Fig. 7.
Stacked bar graph representing the results of the visual assessment for the parameters of artifacts. (a) streak artifact, (b) respiratory motion/pulsation artifact. (a) The images of LAVA Starnavi+ had less streak artifacts than those of LAVA Starnavi−, while no streak artifact in Cartesian LAVAnavi+. (b) The images of Cartesian LAVAnavi+ had stronger respiratory motion/pulsation artifact than those of LAVA Starnavi− and LAVA Starnavi+. There was no significant difference between the score for respiratory motion/pulsation artifact of LAVA Starnavi− and that of LAVA Starnavi+. LAVA, liver acquisition with volume acceleration; LAVA Starnavi-: stack-of-stars LAVA without navigator echoes; LAVA Starnavi+: stack-of-stars LAVA with navigator echoes.
