Magnetic resonance arthrography: Current status

Magnetic resonance imaging (MRI) is frequently considered the best method o f diagnosis in musculoskeletal disorders. Intraarticular fluid improves joi nt assessment by helping to delineate intraarticular structures, separating otherwise closely-apposed structures, and filling potential spaces which l ie within or communicate with the joint. Initially, it was anticipated that plain MRI would replace arthrography. The message from our surgical collea gues is that this ideal has not yet been achieved. Greater precision should reduce the need for more invasive techniques, such as diagnostic arthrosco py which is why direct and indirect MR arthrography are being employed. Thi s article reviews the current status of MR arthrography as an evolving tech nique in the imaging of joint disorders.
