Fig. 1. 32-year-old male potential liver donor. Hand-tracing of liver
outline on axial CT scan acquired during portal venous phase shows isolation
of liver from surrounding tissues of similar attenuation, such as stomach and
spleen. With hand-tracing, care is exercised to exclude vascular structures
such as inferior vena cava (arrowhead), extrahepatic portal vein
(arrow), and major fissures such as fissure for ligamentum teres.

Fig. 2. 32-year-old male potential liver donor. Three-dimensional
model of liver in frontal projection, was generated using commercially
available software after hand-tracing liver outline on axial images, as shown
in Figure 1. Model shows size,
shape, and surface contour of liver. These will determine if graft can be
safely accommodated in recipient's abdominal cavity.

Fig. 3A. 32-year-old male potential liver donor. Three-dimensional
model of right lobe of liver, hepatic veins, and portal vein in frontal
projection showing hepatectomy plane immediately to right of middle hepatic
vein (arrow).

Fig. 4. Scatterplot shows total liver volume (mL) determined by
observers 1 and 2 for 52 potential donors. Note tight correlation between
measurements obtained by 2 observers (r = 0.996; p <
0.0001).

Fig. 5. Scatterplot shows right lobe liver volume (mL) determined by
each observer compared with graft weight (gm). Note tight correlation between
measured volume and graft weight (r = 0.898 and 0.879 for observers 1
and 2, respectively; p < 0.001). + = observer 1, = observer
2.
