Research

Dr. Loeber is interested in functional, metabolic imaging with PET/CT and PET/MRI in companion animals, with a specific interest in oncologic and neuro-oncologic imaging. She is currently running clinical trials evaluating FDG PET/CT in dogs with Blastomycosis and dogs with apocrine gland anal sac adenocarcinoma (AGASACA). She has completed a clinical trial evaluating canine brain tumor patients with PET/MRI. Dr. Loeber is also interested in standing equine CT research, infectious disease imaging, and further evaluation of cross-sectional imaging of exotic animal patients.

Responsibilities

Clinician; course coordinator for fourth year ultrasound elective; veterinary student education; intern and resident training; continuing education for practitioners.

Clinical Interests

Dr. Loeber has a specific interest in cross-sectional imaging including CT and MRI in small and large companion animals, equine, and zoo, exotic and wildlife species.
