Indocyanine green plasma clearance rate and 99mTc-galactosyl human serum albumin single-photon emission computed tomography evaluated preoperative remnant liver

Figure 2 Anatomical volume remnant indocyanine green plasma clearance rate and functional volume remnant indocyanine green plasma clearance rate. A: Changes in anatomical volume remnant indocyanine green plasma clearance rate (a-rem-KICG) and functional volume remnant indocyanine green plasma clearance rate (f-rem-KICG) between pre- and post-portal vein embolization. The increased amount of f-rem-KICG was significantly larger than that of a-rem-KICG (P = 0.0273); B: Scatter plots of a-rem-KICG and f-rem-KICG. The black and white dots show the pre-and post-portal vein embolization (PVE) remnant liver KICGs, respectively. After PVE, 17 patients had a-rem-KICG > 0.05, and f-rem-KICG > 0.05. Six patients (26%) had a-rem-KICG < 0.05, and f-rem-KICG > 0.05. A significant correlation was observed between a-rem-KICG and f-rem-KICG (P = 0.0002, R² = 0.5156). a-rem-KICG: Anatomical volume remnant indocyanine green plasma clearance rate; f-rem-KICG: Functional volume remnant indocyanine green plasma clearance rate; PVE: Portal vein embolization.
