FIGURE. — Pericortical enhancement is visible on postcontrast FLAIR images of a 68-year-old cognitively healthy female participant (case 1). Enhancement is apparent on the regular postcontrast FLAIR scan acquired 16 minutes after contrast administration (A) and even more conspicuous on the heavily T2-weighted FLAIR scan acquired immediately thereafter (B). The sequences were repeated 131 minutes after contrast administration. No signal enhancement is visible on the repeat regular postcontrast FLAIR scan (C), but enhancement is still visible on the repeat heavily T2-weighted FLAIR scan (D).
