WebA fasting serum iron panel was obtained and a magnetic resonance imaging scan with quantitative susceptibility mapping (QSM) was used to quantify brain iron concentrations. Although serum ferritin levels were higher in the AUD group than in controls, whole-brain iron susceptibility did not differ between groups. WebApr 28, 2016 · Efficient implementation of 'Closed-form l2-Regularized QSM', proposed by B. Bilgic et al. Here the susceptibility distribution is calculated that has an optimal balance between: - explaining the measured field (minimal residual) - a smooth appareance (minimal difference between neighbouring voxels)
