Effect of food intake on the tissue distribution of gallium-67: concise communication

Fasting affects the body retention and tissue distribution of Ga-67 in experimental animals. In Ga-67 experiments, therefore, a difference in food intake between treated and control animals might result in confusing side effects. We have observed this in irradiation studies. It is suggested that a fasting regimen should be imposed in any Ga-67 animal study where an alteration in food intake might be experienced in the treated group.
