Inversion-non-Recovery (InoR) method for long-T2 suppression in a steady-state 3D-UTE sequence for short-T2 imaging
Résumé
A novel method for long-T2 suppression in 3D-UTE imaging is introduced. The method is based on long- and short-T2 components phase states in a dual-segment acquisition scheme (digital summation of two k-spaces before reconstruction, respectively acquired with and without adiabatic inversion), and offers a substantial contrast-to-noise ratio over the different components. We compare our method to the state-of-the-art IR-UTE. It shows higher performance and efficiency in terms of signal suppression and short-T2 contrast.
