- This post has been made in conjunction with Dr Joe Thomas, a Senior Consultant Rheumatologist in Kochi India with a vast amount of clinical experience. He also happens to have a very strong interest in Imaging of Arthropathies and has joined us to bring a clinical perspective to the imaging and to advise on what rheumatologists want when we report their referrals.
- This is the first of what will be many joint posts with Joe on Imaging in Arthropathies.
