Reproducibility analysis of FA and axonal fiber orientation. The quantitative analysis of DTI results, including (a) fractional anisotropy (FA) difference and (b) deviation angle. Due to the 1.4 × SNR gain, Wideband results have lower HWHM in both histograms, indicating better reproducibility. The half width at half maximum (HWHM) of whole brain FA difference distribution dropped from 0.072 to 0.041(56.9%), and the HWHM of fiber deviation angle histogram decreased from 25.3° to 16.2° (64%).
