Removal of Arterial Vessel Contributions in Susceptibility-Weighted Images for Quantification of Normalized Visible Venous Volume in Children with Sickle Cell Disease

Figure 4

Box plot of the normalized venous vessel volume (NVVV) in 21 patients with SCD before [uncorrected NVVV (uNVVV) = 0.012 ± 0.005 (mean ± SD)] and after arterial signal correction [corrected NVVV (cNVVV) = 0.008 ± 0.003 (mean ± SD)].
