4. Global cortical atrophy scale for frontal atrophy (4,5)


 

Axial

Grade 0

5. Modified Fazekas scale for white matter hyperintensity (DP system) (6–8)


 

Deep white matter (DWM, D rating) based on the longest diameter of the lesions.
  - 방향에 상관없이 가장 긴 diameter 측정한다
  - Periventricular white matter와의 구분 위해 ventricle의 lateral wall쪽으로는 normal appearing white matter를 사이에 두고 있어야 한다. 

  - Upper margin을 측정 시 마지막 ventricle이 보인 후 위로 두번째 cut (1cm)에서 보이는 white matter change를 grading한다.

 

Periventricular white matter (PWM, P rating) based on the size of the cap and band.

  - capping은 ventricle에 perpendicular한 방향으로, 

  - banding 은 horizontal axis로 가장 큰 diameter를 측정한다.

 

 

 

D1 (<10mm)

D2 (in between)

P2 (in between)
