Abstract:
The anatomy of the Leopard gecko, Eublepharis macularius, and the technique and the diagnostic possibilities of the radiologic and computed-tomographic examination of lizards are summarized in a bibliography. Some aspects of the topographic anatomy of this species are illustrated by one necropsy. The various parts of the gastrointestinal system were identified by histological examinations. 15 preparations of wild captured Leopard geckos were examined radiographically to describe the physiological appearence of the skeleton.15 patients received plain radiographs. 8 different boxes for the immobilization of geckos were tested for practical use. The skeleton and the respiratory tract were fully visible on all x-ray images. The differentiation of the gastrointestinal tract was increased when containing radioopaque material like sand. Eggs with calcified shells were the only detectable parts from the urogenital tract. 2 patients with anorexia and weight loss were administered 0,5 ml of a Gastrografin®-water mixture in the ratio 1:3. The dosage was 2,9 or 4,9 ml Gastrografin/kg respectively. The gastrointestinal tract and the surface of the mucous membrane could be visualized very well. The first excretion of the contrast medium resulted 18 - 34 or 28 - 45 hours respectively after the administration. On one dead Leopard gecko a computed tomographic examination was done. This allowed the 3D-reconstruction of the skeleton. The advantages and disadvantages of the various fixation techniques are discussed. The possibilities of radiologic diagnostic imaging techniques for geckos are described.
