Using a specialised PET scan can help diagnose large vessel vasculitis, particularly in patients who fail to meet American College of Rheumatology diagnostic criteria, a small Australian study suggests.

The scan that uses radioactive glucose can also monitor disease activity, identify occult sites of large vessel inflammation and titrate doses of prednisolone in selected cases, the authors report in the International Journal of Rheumatic Diseases.
