1
Q
Features of T1 weighted MRI images
A
CSF dark, white matter lighter than gray matter, dark vessels (vessels bright if contrast added)
2
Q
Features of T2 weighted MRI images
A
CSF bright, white matter darker than gray matter, orbits bright
3
Q
Features of T2 FLAIR MRI images
A
Gray matter lighter than white matter, CSF dark* (difference from T2)
4

Features of diffusion weighted (DWI) MRI images
A
