Rheumatoid arthritis (RA) is challenging to diagnose, especially in the early stage, because the signs and symptoms are similar to many other conditions. Healthcare providers rely on a physical exam, family medical history, several blood tests, and imaging such as X-rays, MRIs, and ultrasound. MRI and ultrasound images can reveal signs of RA at an early stage and guide your treatment by showing the extent of your joint damage.
