This paper may be of some use, it was published in 1983 so it is
probably not up to date.

Measurement of liver volume by ultrasound and computed tomography.

The summary of the article:
A morphometric method to calculate liver volumes from transverse
sections is evaluated (point-integrating method). In the first part of
the study, 10 liver specimens were investigated by computed tomography
(CT) and ultrasound (US); the calculated volumes were compared to the
volumes obtained by water displacement of the organs. While CT showed
an ideal agreement (r = 0.994), volumes calculated from US sections
correlated less well (percentage differences from +12.5% to -9%, r =
0.915). In the second part of the study, the livers of 10 randomly
selected patients were investigated by CT and US. Liver volumes were
calculated using the point-integration method. Compared to the CT
examination, US results show a good correlation with a correlation
coefficient of r = 0.977. The point-integration method is very
valuable to measure organ volumes from transverse sections. The method
can be applied "offline" to photographic films, data do not have to be
recorded electronically. The time required to calculate the volume of
an organ is comparable to other methods.
