Radiographic Aspects of Rheumatoid Arthritis

– Diagnosis:     – early changes are limited to the soft tissues w/ fusiform swelling and joint effusion;     – juxta-articular osteoporosis may become more generalized w/ dz progression;     – cartilage destruction produces narrowing of the joint;     – erosion of bone occurs characteristically in the metaphyseal region underlying collateral … Read more
