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

Figure 3

Representative original mIP SWI (left column), MIP TOF (middle column), and corrected mIP SWI (right column) images from the qualitative review showing the degree of arterial vessel contamination (a–d) represent scans from patients with SCD with increasing qualitative scores (scores 0 to III, resp.) of hypointense arterial vessel contamination found in the original mIP SWI. The image in (d) demonstrates that the amount of arterial vessel contamination can be quite large. Note the change in the number of hypointense vessels between the corrected and original mIP SWI.
