There are two ways to live: you can live as if nothing is a miracle; you can live as if everything is a miracle.

Research

A major research focus of our group is the application of epidemiologic principles to veterinary imaging to better understand the performance of Roentgen signs (visual cues within the image) as screening tests, diagnostic tests, risk factors and prognostic indicators of disease. The ultimate goal of this type of study is to assess current and new ways of perform medicine to improve patient care.

Individuals within the group have special interest in head and neck imaging (especially neuroimaging, CT/ MRI), feline hyperthyroidism, digital imaging and ultrasonography. Our group also collaborates with many other scientists and clinical groups within the college.

Tutorial
Study design is the planning of how a research project will be conducted in order to get the most legitimate results. This tutorial helps with critical evaluation of the medical literature and designing projects in patient-based research.
