Systemic Lupus Erythematosus (SLE) is an autoimmune disease which can affect hand vasculature. Noncontrast FSD MRA was compared to contrast enhanced (CE) Time resolve (TWIST) and high resolution MRA. Vascular pathology was compared to clinical findings. Preliminary data shows FSD MRA was superior to CE MRA in all segments evaluated. Vascular pathology had variable concordance with clinical presentation which will warrant further investigation.
