A comparison of adjacent sections in SWI magnitude and HP-filtered-phase images at 1.5T and 4T with Duvernoy's india ink-stained results.16 A, Magnitude SWI at 1.5T; B, HP-filtered phase at 1.5T; C, Magnitude SWI at 4T; D, HP-filtered phase at 4T; E, Duvernoy's results. Only 3 unique images from Duvernoy are shown here because his section thickness is 3 mm. The third and fourth images from the top are identical.
