Score
WMH
T1 showed isointensity or low intensity; T2 or T2 FLAIR showed hyperintensity, followed by Fazekas scale (0–6 points) scoring: paraventricular white matter hyperintensity (PVWMH) scoring and deep white matter hyperintensity (DWMH) scoring.
There were round or oval foci in SWI or T2 GRE with signal loss (2∼5 mm < D < 10 mm) but not in other sequences.
≥1 CMB
1
PVS
The gap surrounded the blood vessel or run parallel to the blood vessel, in a line, round, or oval, D < 3 mm, T1 and FLAIR showed low signal, and T2 showed high signal.
PVS in the basal ganglia of grades 2–4
1
Lacuna
There was a lacuna under the round or oval cortex, 3 mm < D < 15 mm, and full of fluid, TIWI, T2WI, and FLAIR showed low signal.
