Quantitative Evaluations of Geometrical Distortion Corrections in Cortical Surface-Based Analysis of High-Resolution Functional MRI Data at 7T.
Although 7T functional MRI (fMRI) provides better signal-to-noise ratio and higher spatial resolution than 3T fMRI, geometric distortions become more challenging because fMRI is more susceptible to distortions than structural MRI. Accurate alignment of 7T fMRI to structural MRI data is critical for precise cortical surface-based analysis. ⋯ 1 TECHNICAL EFFICACY STAGE: 1.
