Professor, Radiology

Ali Guermazi
820 Harrison Ave


Dr. Guermazi is a French board-certified radiologist. Prior to joining Boston University, he was Director of the Osteoporosis and Arthritis Research Group (OARG) at University of California at San Francisco (UCSF) and then Director of Clinical Research at Synarc, Inc. in San Francisco. Dr. Guermazi interest is musculoskeletal diseases, in particular note are his scientific contributions in the diagnosis and disease progression assessment of osteoarthritis using MRI. His work has focused on identifying structural risk factors for developing and worsening osteoarthritis. Dr. Guermazi had been involved in developing several original and widely accepted radiological methods to assess osteoarthritis disease risk and progression, including the WORMS, BLOKS and MOAKS for the knee, HOAMS for the hip and fixed-flexion radiography for measuring joint space width. Dr. Guermazi has been involved as an MRI reader for the past 14 years in several large U.S. studies including the Health Aging and Body Composition (Health ABC) study, the Boston Osteoarthritis Knee study (BOKS), the Multi-center Osteoarthritis STudy (MOST), the Framingham study, Osteoarthritis Initiative (OAI), and other large NIH-funded studies, as well as several Pharmaceutical-sponsored clinical trials. He is author of over 275 peer-reviewed publications and Investigator on numerous research grants related to MRI reading for Osteoarthritis.
