WebApr 20, 2024 · MRI displays contrast that is principally dependent on 3 intrinsic parameters: T 1, T 2, and ρ. For diagnostic purposes, weighted sequences aim to obtain a contrast depending on the nature of the tissue studied by highlighting one of these 3 parameters. The drawback of such an approach is the complex nature of the signal.
