Figure 3 Punctate PML lesions visualized by highly resolving T2 Figure 3 Punctate PML lesions visualized by highly resolving T2*-weighted imaging at 7T (day 4) 7T T2*-weighted images delineate even miniscule punctate lesions in early progressive multifocal leukoencephalopathy (PML). Punctate PML lesions visualized by highly resolving T2*-weighted imaging at 7T (day 4) 7T T2*-weighted images delineate even miniscule punctate lesions in early progressive multifocal leukoencephalopathy (PML). Although the lesion distribution pattern was principally perivascular in appearance (oval) an intralesional central vein was not generally detectable in these microcystic PML lesions despite ultrahigh spatial resolution. Sequence parameters: echo time = 25.0 ms; repetition time = 1,600 ms; spatial resolution = (0.2 × 0.2 × 2.0) mm3. Tim Sinnecker et al.
