Hepatomography: an experimental technique using an emulsifier

Hepatomography was performed by injecting emulsified Ethiodol into the hepatic artery of 9 beagles. The hepatogram was dense and remained long enough for diagnostic tomography. Contrast material was eliminated in part through the kidneys and disappeared from the liver within 24 hours after injection. The dogs were sacrificed 36 hours to 4 months after contrast injection. Longlasting ill effects were observed in only one dog which died of hepatitis. The death of this prompted the use of a more dilute emulsion which was beeter tolerated by all subsequent animals.
