Small-Animal Imaging

The ultimate value of imaging lies primarily in the benefit it brings to human lives. And that potential benefit is first determined by studies in animals. “Hand-me-down” human imaging systems lack the resolution and speed needed for such small animals with high metabolic rates. In the University of Arizona Radiology Research Group, we develop and test systems made specifically to detect submillimeter lesions in toothpick-size mouse femurs or gate to heart rates of over 600 beats/minute. Not only does this have direct clinical application (hand held detector), but it allows for imaging capabilities in a wide spectrum of studies. Research projects that previously depended on large numbers of animals can now get more accurate information using intermittent imaging of fewer animals.

At the University of Arizona Radiology Research Group, we are aware that excellent research depends on excellent animal care. Our professional and support staff include researchers, physicians, veterinarians, and technicians experienced in animal anesthesia, surgery, and husbandry. State-of-the-art monitoring equipment helps assure that individual animals are maintained at optimal physiological parameters. And a vast array of anesthetic protocols, including both gas and injectible anesthetics, are available to meet each investigator’s needs.
