For a number of years conventional radiography was considered the gold standard for tracking RA-related joint disease and the effectiveness of its treatment regardless of sex, although women are 2 to 3 times more likely to be effected by RA. However the sensitivity of this imaging technique is such that the pathology may not be fully appreciated until it's in an advanced stage and likely to not be as responsive to therapy.

In the early 1980's, MRI (magnetic resonance imaging) began to emerge as a more sensitive means of monitoring and detecting early stages of rheumatoid and osteoarthritis. MRI properly assesses rheumatic disease activity, defining the site and extent of lesions. And, with early detection and treatment, a patient's prognosis can be significantly improved.

In the mid 90's, extremity MRI systems became available. However, it is only recently that office-based Rheumatologists have discovered the utility of these systems. Extremity MRI allows the patient to undergo their exam in comfort within their doctor's office without the claustrophobic reactions that large, whole body scanners evoke. And, in most cases, positioning the patient on the extremity MRI system was much less painful than on full body systems.
