FIG 1. Patient without cerebrovascular disease or relevant hemodynamic alterations.
A, An stdTTP map obtained using DSC-MR imaging with a T2*-weighted echo-planar fast-field–echo sequence (74/30/1 [TR/TE/excitations]) with a 30° flip angle, a 240-mm field of view and a 128 x 128-voxel acquisition matrix of. Central parts of vascular territories are displayed in yellow (time step 1, voxels with short stdTTP) and border zones in dark red (time step 5 and 6, voxels with long stdTTP) color. Each color step codes a time interval of 0.5 s.
B, Corresponding T1-weighted image (500/15/2) after IV administration of contrast medium.
