FIG 1. Axial T2-weighted RARE (3300/98/1) (A), PD-weighted RARE (3300/16/1) (B), T1-weighted CSE (768/14/2) (C), and fast FLAIR (9500/119/1) (D) images of the brain of a patient with relapsing-remitting MS. On dual-echo RARE images (A and B), several hyperintense lesions are visible, and some of them are hypointense (black holes) on the corresponding T1-weighted image (C). On the fast FLAIR image (D), the areas of increased signal correspond well to the hyperintense lesions visible on the RARE images
