Presente y futuro de la ecografía en las espondiloartritis.

Today ultrasound in spondyloarthritis is being developed in three main areas. Joint ultrasound is similar to that described in rheumatoid arthritis and other synovitis, with extensive literature on the matter. Enthesis ultrasound has a growing number of publications that describe the main elementary lesions. Several ultrasound enthesis scores have been developed that provide an overall view of the patient status and this information is useful both in the field of diagnosis and in assessing disease activity. The sacroiliac joints have also received attention and the published sensitivity and specificity could be useful in clinical practice. The future is unknown, but ultrasound has many possibilities that include improving the reliability, the incorporation of enthesis ultrasound assessment to the diagnostic classification criteria as well as the likelyhood developing simplified scores.
