Long-T2 suppression based on saturation and diffusion in a steady-state 3D-UTE sequence
Résumé
A new method for long-T2 suppression in a prepared steady-state 3D-UTE sequence is introduced. The method is based on long-T2 signal behavior in steady-state as the diffusion-inducing spoiling gradients are modified, giving a theoretical signal cancellation using appropriate coherence combinations. At the same time, short-T2 signal quantity is optimized, offering a positive contrast over this component. Imaging experiments over a Lego brick soaked in doped water show an excellent agreement with theoretical predictions.
