Synopsis

Using a 3T ioMRI system with an 8-channel intraoperative coil, we developed passive sensorimotor intraoperative fMRI protocol under anaesthesia at our site. We successfully applied it to passive fMRI of hand and foot in an exploratory cohort of four patients, confirming correspondence of activation to preoperative fMRI scans. This is the first reported implementation of intraoperative 3T passive fMRI.
