3D Volumetric Nerve-Sheath Weighted RARE Imaging

3D Volumetric Nerve-Sheath Weighted RARE Imaging

High-Resolution 3D Volumetric Nerve-Sheath Weighted RARE Imaging (3D SHINKEI). 3D SHINKEI technique combines fat-suppression pre-pulse (SPectral Attenuated Inversion Recovery: SPAIR) for uniform fat signal suppression, iMSDE preparation for signal suppression from vessels, and 3D variable refocusing flip-angle RARE readout segments for contrast-efficient T2-weighted images. Furthermore, iMSDE pre-pulse was based on T2-preparation (T2-prep) pulse and therefore T2-contrast is affected by preparation duration (iMSDE-prep). 3D-SHINKEI technique will be made possible to nerve-sheath depiction.
