Abstract

Radiography is the most widely utilized imaging modality for measuring joint damage in early rheumatoid arthritis. Conventional radiography is, however, insensitive for showing bone erosions and is totally unsuitable for assessing synovial inflammation. The recognition of these limitations has led to intense interest in ultrasonography and magnetic resonance imaging for assessing synovitis and bone erosions. Magnetic resonance imaging allows detection of bone marrow edema, which is considered to be a very early marker of inflammation as well as a “forerunner” of erosions.

Keywords:
Magnetic resonante
Sinovitis
Early diagnosis
Joint erosion
Resumen

Las radiografías continúan siendo la técnica más utilizada para evaluar el daño articular en la artritis reumatoide precoz. Sin embargo, su baja sensibilidad en la detección de erosiones y la imposibilidad de identificar la sinovitis ha propiciado la introducción de otras modalidades de diagnóstico por imagen, como la ecografía y la resonancia magnética (RM), que permiten la identificación directa de la inflamación sinovial y de las erosiones. La RM tiene la ventaja de permitir el diagnóstico del edema óseo, que se considera como un marcador precoz de inflamación activa y un precursor de la aparición de nuevas erosiones.
