WebMar 28, 2024 · Although multiecho fMRI requires a larger voxel and/or a longer time of repetition (TR) than the standard fMRI sequence for multiple readouts [e.g., ∼4-mm iso-voxel and TR of 2 s in multi-echo ... WebAug 1, 2024 · In a typical single-echo fMRI sequence, images are acquired once per tissue excitation after a single fixed delay (‘echo time’; usually near 30 ms at 3 T). Multi-echo acquisitions collect three or more images per volume at echo times spanning tens of milliseconds (ranging approximately from 10 to 90 ms at 3 T).
