Brief Summary


  1. To assess the validity of non-gadolinium techniques for evaluation of peripheral arteries as compared to conventional gadolinium MRA, nail bed capillaroscopy, and photoplethysmography.
  2. To assess the severity of arterial disease in patients with vasculitides, RP, or scleroderma, as compared to age-matched controls.
  3. To assess the peripheral arteries by non-gadolinium and gadolinium MRA, nail bed capilloaroscopy, and photoplethysmography while patients are on therapy compared to off therapy or before and after therapy, including pharmacologic or hyperbaric therapy.
