Our staff veterinarians and technicians at PEH are trained and experienced in obtaining quality radiograph images of your animals and ultrasound use in scenarios common to emergency cases.

Through telemedicine, our digital radiographs, if needed, are sent to a boarded radiologist for review and comment with 24/7/365 access to review in less than 1 hour.

In the event an ultrasound case requires more advanced skills and knowledge, we consult with area mobile radiologists who are available for ultrasound with prior coordination. Our staff works closely with these radiologists to work towards a diagnosis and treatment plan for your cat or dog.
