In this special episode of VF's Vasculitis Visionaries, Ben and Kaley speak with well-known vasculitis researcher, Dr. Peter Grayson. A staple at VF events and symposiums, Dr. Grayson is the head of the Vasculitis Translational Research Program (VTRP) at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS). Dr. Grayson discusses the VTRP team's ongoing research, including a new cohort study on relapsing polychondritis (RP), a disease characterized by cartilage inflammation that presents similarly to GPA. He also gives Ben and Kaley a lesson in "PET scans 101" and discusses an upcoming research announcement that could be a real gamechanger.
