Diagnostic role of anti-RA33 autoantibody in early rheumatoid arthritis. does MRI improve the diagnostic sensitivity?

ABSTRACT

Introduction: There are inherent difficulties in making an accurate diagnosis or RA in early stages. The Aim of This Study was to determine the value or the anti -RA33 antibodies alone or in combination with MRI for the diagnosis or early RA and for the differential diagnosis of unclassified arthritis. Also, a comparison of ultrasonography, magnetic resonance imaging and plain radiography in their sensitivities for detection of early joint pathology in early RA was revised
