We have shown that it is possible to detect neural activity using fMRI and PRESTO-CAN, a previously developed MRI reconstruction method based on golden angle hybrid radial-Cartesian sampling of k-space. The neural activity appears to be comparable with what can be obtained using a 3D PRESTO Cartesian sequence. However, we have not yet utilized all the facilities of PRESTO-CAN, such as the hourglass filter. The PRESTO-CAN sequence investigated here is able cover the whole brain for fMRI examinations with sufficient temporal resolution.
