Figures
- Fig 1.
A, 65-year-old patient. Axial FLAIR. There is subcortical white matter hyperintensity (arrows) that is isointense to the caudate nucleus, classified as “mildly hyperintense” and graded as “1.
B, Axial FLAIR. Signal intensities at the caudate nucleus and insular cortex in the same patient with grade 1 SWM hyperintensity.
- Fig 2.
A, 76-year-old patient. Axial FLAIR. There is subcortical white matter hyperintensity (arrows) which is isointense to the insular cortex, classified as “distinctively hyperintense” and graded as “2.”
B, Axial FLAIR. Signal intensities at the caudate nucleus and insular cortex in the same patient with grade 2 SWM hyperintensity.
- Fig 3.
61-year-old patient. Axial FLAIR. There is absence of subcortical white matter hyperintensity.
- Fig 4.
65-year-old patient. Axial FLAIR. There is a hypointense line in the precentral gyrus gray matter (arrows), designated “1.”
- Fig 5.
61-year-old patient. Axial FLAIR. There is absence of a hypointense line in the precentral gyrus gray matter, designated “0.”
