Mature fibrous tissue on T2 is which signal intensity?

Explanation:
On T2-weighted MRI, fluids and edema appear bright, while dense collagen-rich fibrous tissue has very short T2 relaxation times and thus shows low signal. Mature fibrous tissue is water-poor and tightly packed with collagen, so it appears dark on T2. This is why mature scar or dense ligamentous tissue tends to be dark, in contrast to bright fluid or edema.
