Clinical staging and gadolinium-DTPA enhanced images of the wrist in rheumatoid arthritis

J Rheumatol. 1993 May;20(5):781-4.

Abstract

The usefulness of gadolinium (Gd)-DTPA enhanced magnetic resonance imaging (MRI) of the wrist joint for predicting articular destruction was investigated in 49 patients with rheumatoid arthritis (RA). On T1 weighted images with Gd-DTPA enhancement, the synovium showed a localized or diffuse pattern of enhancement. Many patients classed as stage II or higher by plain radiography had diffuse enhancement on MRI, while all except one stage I patient had relatively confined localized enhancement. Our study showed that MRI of the carpus could detect soft tissue changes in patients with RA earlier than anything revealed by radiography, and suggested that contrast MRI may be useful for predicting articular destruction.
