Response Letter to Dr J.A. Impellizeri

Authors


Dear Editor

I would like to respond to the letter of Dr J.A. Impellizeri with regard to our article “Hepatic volume measurements in dogs with extrahepatic congenital shunts before and after surgical attenuation” in J Vet Intern Med (2010;24:114–119). We acknowledge that the conclusion “CT is the preferred imaging method for volumetric estimation because of speed” is limited to the diagnostic imaging equipment that was used in this study. This could have been stated more clearly. However, accuracy is not identical to a presumably improved reliability of volume measurements but depends on the deviation of the measurements with real organ volumes, and we are not aware of a generally accepted gold standard for liver volume in living dogs.
