Dataset supporting: Single-Shot 2D Radial Echo Planar Imaging for Functional MRI

Dataset supporting: Single-Shot 2D Radial Echo Planar Imaging for Functional MRI This dataset provides the raw **k-space data** and associated sampling information (readout trajectory, golden-angle rotations, etc.) acquired with the novel single-shot 2D radial echo planar imaging (ss-rEPI) sequence developed for distortion-free functional MRI at 3T. The data are prepared for direct use with the corresponding reconstruction code available at: https://github.com/crettenm/ss-rEPI Publication The data support the results presented in: Rettenmeier, C. A., Yu, Z., Edwards-Calma, K., Block, K. T., & Stenger, V. A. (Year). Single-Shot 2D Radial Echo Planar Imaging for Functional MRI. *Journal Name* (in press / published). DOI: [insert the paper's DOI here once available] Contents - Three multi-gradient-echo k-space datasets from ss-rEPI acquisitions: • `prep_data_Sub001_fMRI_2mm.mat` — fMRI dataset at 2 mm in-plane resolution • `prep_data_Sub002_struct_2mm.mat` — structural dataset at 2 mm in-plane resolution • `prep_data_Sub002_struct_rampsamp.mat` — structural dataset at 1.5 mm in-plane resolution (ramp-sampled) All datasets include the corresponding sampling trajectory and parameter information needed for reconstruction. For detailed methods, image reconstruction parameters, experimental setup, and results, please refer to the associated publication. A full README with file descriptions and usage instructions is included in the GitHub repository.
