Ultrahigh-Field MR (7 T) Imaging of Brain Lesions in Neuromyelitis Optica

Figure 1

Examples of typical lesions in NMOsd. Brain lesions on T2*-weighted GRE images with in-plane resolution of 0.2 × 0.2 mm² in six patients with NMO. Most lesions (approximately 85%) (arrows in (a), (b), (c), (d), and (e)) are small, round-shaped, and located in subcortical regions without typical sign of central venule or perivenous migration as seen in MS lesions. Only a few lesions have visible central veins (arrowhead in (d); this particular lesion was seen in enhance with gadolinium on a conventional brain MRI study performed three years previously). Only 3% lesions are juxtacortical (long arrow in (f)).
