Determination of liver, kidney, and spleen volumes by computed tomography: an experimental study in dogs.

The volume of the dog's liver, kidneys, and spleen were measured by computed tomography (CT) and a water displacement method. Organ volume determination by CT is a rapid, simple procedure that is accurate to +/- 5% of the organ volume measured by water displacement. Individual measurements were reproducible to within +/- 3%. Determination of organ volume has potential importance in a variety of clinical situations.
