The rate of clearance of radioactive xenon (‘33Xe) from a joint (St Onge, Dick, Bell and Boyle l968a ; Dick, Whaley, St Onge, Downie, Boyle, Nuki, Gillespie and Buchanan l970b) has been shown to reflect the degree of inflammatory involvement of the joint at the time of study, and has been used to measure synovial blood flow in the human knee (St Onge, Dick, Boyle, Jasani, Whaley, Pack and Bucha...
