The method is able to image similar repeating events with subsecond temporal resolution. Here, we demonstrate the use of EVER-SWIFT for detecting functional MRI responses during deep brain stimulation of the medial septal nucleus and during spontaneous isoflurane-induced burst suppression in the rat brain at 9.4 T with 200-ms temporal resolution.<h4>Results</h4>The EVER-SWIFT approach showed that the shapes and time-to-peak values of the response curves to deep brain stimulation significantly differed betweMagnetic resonance in medicineEvent-recurring multiband SWIFT functional MRI with 200-ms temporal resolution during deep brain stimulation and isoflurane-induced burst suppression in rat.PMC9160777R01 MH127548P41 EB027061U01 NS103569U01‐NS103569‐01P41EB027061691110Mangia SPirttimaki TPaasonen JWu LIdiyatullin DLaakso HGrohn OPaasonen ELehto LJMichaeli SMa JTanila HfalseEvent-recurring multiband SWIFT functional MRI with 200-ms temporal resolution during deep brain stimulation and isoflurane-induced burst suppression in rat.<h4>Purpose</h4>To develop a high temporal resolution functional MRI method for tracking repeating events in the brain.<h4>Methods</h4>We developed a novel functional MRI method using multiband sweep imaging with Fourier transformation (SWIFT), termed event-recurring SWIFT (EVER-SWIFT).
