A Corrigendum on
The Influence of Radio-Frequency Transmit Field Inhomogeneities on the Accuracy of G-ratio Weighted Imaging
by Emmenegger, T. M., David, G., Ashtarayeh, M., Fritz, F. J., Ellerbrock, I., Helms, G., Balteau, E., Freund, P., and Mohammadi, S. (2021). Front. Neurosci. 15:674719. doi: 10.3389/fnins.2021.674719
In the original article, there was a mistake in Figure 5 as published. The MVF map was shown twice in the original figure (middle and bottom rows), instead the AVF map should have been depicted in the middle row. The corrected Figure 5 that appears below.
Figure 5. Voxel-wise maps of group-averaged gB1MR, AVFB1MR, and MVFB1MR, restricted to the group WM mask (cf. section “Definition of White Matter Masks”). Depicted are a single sagittal (x = 100), coronal (y = 91), and axial (z = 85) slice.
In the published article, there was an error regarding the affiliation for Isabel Ellerbrock. As well as having affiliation 3, she should also have 2. There was an error regarding the affiliation for Gergely David. As well as having affiliation 1, he should also have 2.
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
