Maybe: It can show arthritic changes suggestive of ra, but other forms arthritis can mimic these changes. A blood test is less expensive and can diagnose ra.

Can indicate: Mri of knee or ankle joint may shows signs of arthritis (fluid, synovitis, cartilage lost, erosions) but these signs are not specific for rheumatoid arthritis. Ra is diagnosed by blood tests and clinical history as is spondyloarthropathy.

Yes: Mri can spot early erosive changes suggesting ra. Ultrasound can do this as well but at a much lower cost. The first thing is evaluation by a rheumatologist and having appropriate lab has been done.

Can I bathe my baby when he has tender skin spots on his hands and feet, etc?

Yes: It is ok to bathe your baby, even with tender spots or a rash. However if your baby seems really uncomfortable you may want to make an appointment with your pediatrician. Remember babies do not need a bath every day- this could dry out their skin and make it prone to peeling or increased tenderness. Instead, bathe every 2-4 days.

CT vs MRI: Ct's and mris can focus on different things. Ct is typically used to view bone and look for bleeding while mris are used to view tissues. Also, cts use radiation similar to xrays while and MRI does not expose the patient to any radiation. However, anyone with a magnetic metal in their body can not get an mri, since MRI uses a large magnet.

Not usual for disk: With the muscular atrophy and neuritis, it might be best to undergo further testing. There are many possible causes, including diabetes, autoimmune, endocrine, to mention a few. At your age, a complete workup is indicated.
