The differential absorption, in the hind limb and neck was evaluated in six Atlantic ridley turtles. A commonly used excretory uroqraphic iodinated contrast material was injected subcutaneously and serial radiographs were obtained. The 5-min and 70-min films were evaluated independently by five radioloqists. The data obtained were compiled and the mode, mean, and range for the hind limb and neck absorption rates were analyzed. The neck site showed more rapid absorption than did the hind limb. Further, the area of the urinary tract was serially radiographed in these animals to evaluate whether the urographic contrast agent would opacify the tract. No opacification of the kidneys was seen on serial films made up to 2h hr after injection.
