Functional magnetic resonance imaging (fmri) methodology using transverse relaxation preparation and non-echo-planar imaging (epi) pulse sequences

摘要: An embodiment in accordance with the present invention provides a new acquisition scheme for T2-weighted BOLD fMRI. It employs T2 preparation module to induce contrast, followed by single-shot 3D fast gradient echo (GRE) readout short time (TE<2ms). The separation of contrast generation from substantially reduces "dead time" due long TE required spin (SE) sequences. This approach termed "3D T2prep-GRE," can be implemented any magnetic resonance imaging machine, known or conceivable one skill art. is expected useful ultra-high field fMRI studies that require whole brain coverage, focus on regions near air cavities. concept using generate combined many other sequences at strength.
