Equine Bone Scintigraphy: What is it and what can it do for me?

Introduction: Nuclear Scintigraphy is a highly sensitive, alternative imaging modality used in human and veterinary medicine. This modality involves the administration of a radioactive substance (radioisotope) to a patient. Generally, the radioisotope is labeled to a specific compound. This labeled combination is known as a radiopharmaceutical. These radiopharmaceuticals are formulated in various chemical forms that will allow them to localize in specific organs (e.g., bone, kidneys, liver). The most common radioisotope label is technetium-99m (Tc). Other radioisotopes used include iodine-123, iodine131, indium-111, thallium-201, and gallium-67. Each radioisotope has different imaging characteristics. The radioisotope and the radiopharmaceutical used depend upon the study performed and the target organ.
