Contrast media for computer tomography of the liver.
A simple phantom experiment indicates that the enhancement of abdominal organs should be twice the SD of noise in a CT image. The enhancement of liver tissue by urographic and biligraphic contrast media is analysed in clinical series and animal experiments. Various substances, applied alone and in combination, were investigated. At present, only the infusion technique of urographic media provides a sufficient enhancement of liver tissue.
