Keywords: Functional Connectivity, fMRI, dual FOV
Motivation: Functional neuroimaging target either the brain or the spinal cord, but usually not both because simultaneous acquisitions from distant fields of view are challenging with conventional MRI.
Goal(s): To establish a novel MRI approach for artefact-free, quiet fMRI simultaneously from brain and spinal cord, avoiding the need of dynamic shimming.
Approach: Our approach is to use MB-SWIFT in a simultaneous dual-FOV configuration with a Dual Amplifier Blanking Selector Unit (DABSU) that employs two transmitters and two receiver channels.
Results: The results established feasibility of the novel approach for task-based fMRI and connectivity analyses between lumbar spinal cord and brain in rat.
Impact: The method could be used for unprecedented investigations of the central nervous system, and could be extended to any two separate parts of the body.
