Figure 2

Cortical lesions. Two subpial lesions are well seen on a motion and B0-corrected, 3D 0.5-mm3 T2*w GRE image (A, total acquisition time ∼35 min. for three slabs covering the supratentorial brain) and on a median of 3 acquisitions of 0.5-mm3. MP2RAGE (B, ∼10 min/acquisition). Lesions are visible, but less well seen on a 0.7-mm3. MP2RAGE image (acquisition time ∼10 min). (D) and (E) A subpial lesion visualized on 0.7-mm3 MP2RAGE but less well seen on a 0.8-mm3 T2*w GRE image (acquisition time ∼8 min). (F) A subpial lesion visualized on a 2D T2*w GRE image (0.2 mm2 in-plane resolution, 1 mm slice thickness, ∼24 min acquisition time for three slabs covering the supratentorial brain). Images in red boxes are magnifications of the regions outlined in red on whole-brain images above. A comparison of 7T (G–I) and 3T (J–L) images in the same MS subject. Arrows indicate locations of CLs as seen on MP2RAGE (G, J), FLAIR (H, K) and T2*w GRE (I, L).
