High-resolution spiral fMRI acquisition at 7 Tesla is shown with excellent image quality and geometric veracity. Both, high-resolution spiral-out (1mm isotropic) and multi-echo spiral-in/out readouts (1.5mm) are acquired in a visual paradigm, performed by 2 subjects. The datasets are analyzed by SPM and activation patterns are shown overlaid over the actual fMRI datasets of almost structural imaging quality.
