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

Figure 1 Calculation of remnant liver indocyanine green plasma clearance rate. A: 3D volume analysis using SYNAPSE VINCENT^®, remnant liver anatomical volume rate: 53%; B: A 99mTc-galactosyl human serum albumin single-photon emission computed tomography (99mTc-GSA SPECT) image; C: A fused 99mTc-GSA SPECT and 3D volume analysis (using SYNAPSE VINCENT^®) image, remnant liver functional volume rate: 65%. The remnant liver indocyanine green plasma clearance rate (KICG) is calculated as follows: A-rem-KICG = remnant liver anatomical volume rate × KICG and functional volume remnant KICG (f-rem-KICG) = remnant liver functional volume rate × KICG. In this case of a right hepatectomy, a-rem-KICG = 0.53 × 0.087 = 0.047, f-rem-KICG = 0.65 × 0.087 = 0.057.
