AVMI_TustinAdvanced Veterinary Medical Imaging (AVMI) is a state-of-the-art diagnostic imaging center providing digital radiography, multi-slice CT, high field (1.5 Tesla) MRI, and ultrasonography as well as both diagnostic and therapeutic nuclear medicine. In 1986 AVMI became the first private practice veterinary facility to provide radioactive iodine therapy for the treatment of feline hyperthyroidism. Today, AVMI is one of a very few facilities in the United States that offer radioiodine therapy for canine thyroid carcinoma.
