hyperintensity from T-3 to the conus medullaris. Pulsation artifact dorsal to the cord and cord swelling obscuring visualization of the dorsal flow voids in this patient, who was presumed to have an AVF. B: Sagittal T1-weighted image with Gd demonstrating patchy linear enhancement from T-3 to T-12. There was no significant vascularity dorsal to the cord. C: Sagittal myelographic 3D CISS image demonstrating flow voids posterior to the cord, better seen when reformatted in a volume viewer. D: Oblique coronal reformat of the sagittal PC-FIESTA image along the dorsal aspect

of the first-harmonic curl data to the local noise. A separately acquired 3D T1-weighted volume with approximately 1-mm isotropic sampling was used to generate 2 ROIs: tumor and surrounding brain tissue. The T1 image was automatically segmented as described by Jack et al. 5 to estimate the gray matter, white matter, and CSF content at each voxel. The boundary of the tumor was manually traced on the T1 image. The T1 image along with the tumor mask and segmentation images were then registered and resliced to the MRE data. Trilinear interpolation was used for
