Abstract
Background: Rheumatoid arthritis is a multisystem dis-order. Over the past decades, significant improvement in its management owing to development of new diagnostic tech-niques. Ultrasound allows identification of joint effusion, lesions affecting tendons, ligaments as well as inflammatory diseases of the tendons, subclinical synovitis and bony erosion in the setting of rheumatoid arthritis. MRI allows the detection of bone marrow edema, erosions in early rheumatoid arthritis as well as a marker of active inflammation.
Aim of Work: The aim of this study is to evaluate the diagnostic performance of both ultrasonography and MRI findings in evaluation of rheumatoid arthritis of the wrist. We will highlight both the strengths and weaknesses of these two imaging modalities.
Patients and Methods: This study included fifty patients; 30 females, 20 males with age range from 21 to 75 years. All patients were presenting with wrist joint pain and inflammatory signs (red, hotness and joint swelling). This study was per-formed in the period from June 2014 till January 2016. All patients were subjected to the full history taking, full exami-nation, plain X-ray examination, high resolution ultrasound examination using high frequency linear probe, dynamic ultrasound when needed, color Doppler and/or power Doppler study and MRI (1.5 T) examination with or without IV contrast according to the indications.
Results: Statistical analysis of the results showed a highly significant agreementbetween both MRI and ultrasound in the detection of synovial thickening, pannus formation and inflammation.
