## Abstract The aim of the present study was to assess and to compare the orbital and retinal vascular flow dynamics and resistance in patients with homozygous sickle cell disease with controls by means of duplex and color Doppler ultrasonography. Fortyβsix patients with homozygous sickle cell dise
Steady-state arterial spin tagging approaches can provide quantitative images of CBF, but have not been validated in humans. The work presented here compared CBF values measured using steady-state arterial spin tagging with CBF values measured in the same group of human subjects using the H(2)(15)O
