Background:
Rheumatoid arthritis is a debilitating and destructive disease for which limited therapeutic options exist.
Objective:
This report summarizes serial magnetic resonance imaging (MRI) findings from nine study participants treated with hyperbaric oxygen (HBO2) therapy and expands upon an earlier pilot study that showed improvement in disease activity and joint pain as determined by multiple, validated clinical measures.
Methods:
Rheumatoid arthritis patients received 30 hyperbaric oxygen treatments over six to 10 weeks. MRI with and without contrast was completed at baseline, and at three- and six-month intervals following initiation of HBO2 therapy. Ratings were based on Outcome Measures in Rheumatology Clinical Trials (OMERACT) Rheumatoid Arthritis Magnetic Resonance Imaging Score (RAMRIS) criteria, the standard method for quantification of inflammation and damage by MRI in RA trials.
Results:
Using RAMRIS criteria, nine of nine patients demonstrated no radiologic progression of erosions, synovitis, or bone marrow edema at three- and six-month scans.
Conclusion:
Our findings suggest that HBO2 therapy may be useful as an adjunctive or alternative treatment to disease-modifying drugs for rheumatoid arthritis.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
