Improvements in the Quantitative Assessment of Cerebral Blood Volume and Flow with the Removal of Vessel Voxels from MR Perfusion Images

Figure 3

Case 1. Rescaled CBV images (first row), rescaled CBF images calculated using the sSVD (second row) and cSVD (third row) techniques, and rescaled MTT images calculated using the sSVD (fourth row) and cSVD (fifth row) techniques. The images are displayed using the whole brain mask before the removal of the CSF and vessel voxels (first column), after the removal of the CSF voxels (second column), after the removal of the vessel voxels (third column), and after the removal of both the CSF and vessel voxels (fourth column).
