Radiology

Research + Clinical Trials

As part of a major academic medical center, the Radiology Department considers research to be an important part of its mission. Our radiologists are regularly exploring innovative new uses of imaging technologies. They also actively collaborate with Tufts MC colleagues who are conducting clinical research on a variety of diseases with an imaging component, including osteoarthritis and fatty liver disease.
