Abstract
Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by proliferative synovitis and inflammatory arthritis with erosions. RA targets multiple peripheral joints including the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints. Conventional radiography is still important, but recently, imaging of RA has been dramatically changed by magnetic resonance imaging (MRI) and ultrasonography (US). In this book, we aim to provide comprehensive understanding of RA by ABCDEFGH’s new approach. A: alignment, B: bone, C: capsula articularis, intra-articular, D: distribution, E: extra-articular, F: further information, G: goal, and H: healing.
