Knee cartilage quality assessed with dGEMRIC in rheumatoid arthritis patients before and after treatment with a TNF inhibitor.
BACKGROUND: TNF-α inhibitors are potent anti-inflammatory drugs that have revolutionized the treatment of rheumatoid arthritis (RA). Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a non-invasive method to study cartilage quality, in particular the glycosaminoglycan (GAG) content. PURPOSE: To evaluate knee cartilage quality before and after treatment with a TNF-α inhibitor (infliximab) i
