One of the most devastating complications in children with sickle cell disease is stroke. A hessian-based vessel segmentation algorithm was used on SWI to quantify the venous contrast in patients and normal controls. The conspicuity of venous contrast in sickle cell disease is qualitatively less than in controls and shows a significant quantitative decrease. Quantitative measures of venous contrast inversely correlated with basilar tortuosity.
