Box plots of the SIRliver/spleen (a) SIRliver/lesion (b), and SIRliver/PV (c). (a) The SIRliver/spleen of LAVA Starnavi− was higher than that of Cartesian LAVAnavi+ and LAVA Starnavi+. There was no significant difference between the SIRliver/spleen of Cartesian LAVAnavi+ and that of LAVA Starnavi+. (b) The SIRliver/lesion of Cartesian LAVAnavi+ was lower than that of LAVA Starnavi− and LAVA Starnavi+. There was no significant difference between the SIRliver/lesion of LAVA Starnavi− and that of LAVA Starnavi+. (c) The SIRliver/PV of Cartesian LAVAnavi+ was also lower than that of LAVA Starnavi− and LAVA Starnavi+. There was no significant difference between the SIRliver/PV of LAVA Starnavi− and that of LAVA Starnavi+.
