WebT2-weighted image – Anatomy (spine) T2 images are a map of proton energy within fatty AND water-based tissues of the body. Fatty tissue is distinguished from water-based tissue by comparing with the T1 images – anything that is bright on the T2 images but dark on the T1 images is fluid-based tissue. For example, the CSF is white on this T2 ... WebThat is the reason it is recommended to assess cortical CMIs on 3D T1 weighted images, with confirmation on FLAIR and T2 (if available), and in case of doubt T2*.
