| الوصف: | Purpose To introduce a class of fast 3D quantitative MRI (qMRI) schemes (RESUMEN, for N = 1 , … , 4 ) that allow for a thorough characterization of microstructural properties of brain tissues. Methods An arbitrary multi-echo GRE acquisition optimized for quantitative susceptibility mapping (QSM) is complemented with an appropriate low flip-angle GRE sequence drawn from four possible choices. The acquired signals are processed to analytically derive the longitudinal relaxation ( R 1 ) and free induction decay ( R 2 ∗ ) rates, as well as the proton density (PD) and QSM. A comprehensive modeling of the excitation and B 1 - profiles and of the RF-spoiling is included in the acquisition and processing pipeline. Results The RESUMEN maps appear homogeneous throughout the field-of-view and exhibit comparable values and high SNR across the considered range of N values. Conclusions The introduced schemes represent a class of robust and flexible strategies to derive a thorough and fast qMRI study, suitable for a whole-brain acquisition with isotropic voxel resolution of 700 μ m in less than 15 min. |
