This diagnostic test involves the use of the radioactive isotope Technetium-99 (Tc99). This substance is subject to the Radiation Protection Ordinance, which regulates the safe handling of this material and also the living beings treated with it. It states that animals administered Tc99 are not permitted to come into contact with unauthorised individuals for approx. 48 hours. The exact amount of time is determined by the level of radiation. Your horse is therefore placed in a specially protected stall with other horses that are also in the clinic for scintigraphy scans. Authorised staff members take care of your horse’s well-being. Video monitoring also ensures that your horse is well. However, for your own safety, you as the owner are not permitted to visit your horse during this time. The horse is also not permitted to leave the stall – apart from for the examination itself. There are no exceptions to these rules.
