Using the PROPELLER-EPI technique for functional magnetic resonance imaging has the advantage that, albeit the multi-shot nature of the method, acceptable temporal resolutions can be achieved. At the same time the readout train length is significantly reduced, enabling high in-plane resolutions. In our work we demonstrate that long-axis PROPELLER-EPI can be used for performing fMRI with submillimeter resolution at a clinical field strength of 3T. Results from a finger tapping experiment are presented with an in-plane resolution of 0.7 mm2
