A Corrigendum on
RAFF-4, Magnetization Transfer and Diffusion Tensor MRI of Lysophosphatidylcholine Induced Demyelination and Remyelination in Rats
by Holikova, K., Laakso, H., Salo, R., Shatillo, A., Nurmi, A., Bares, M., et al. (2021). Front. Neurosci. 15:625167. doi: 10.3389/fnins.2021.625167
In the original article, there was a mistake in Figures 2 and 4 as published. In both figures, radial diffusivity (RD) maps were accidently changed to incorrect ones in the final phase of Figure production. The corrected Figures 2 and 4 below. All quantitative analysis and data interpretation was performed using correct RD maps.
FIGURE 2
Figure 2. Quantitative MRI maps in the demyelination phase, on day 3: RAFF4 (A), magnetization transfer ratio, MTR (B), T1sat (C), mean diffusivity, MD (D), fractional anisotropy, FA (E), axial diffusivity, AD (F), radial diffusivity, RD (G), T2w image with lesion (H) and representative example of ROIs for analyzing the lesion on a grayscale RAFF4 map (I). White arrow points to the lesion in the corpus callosum.
FIGURE 4
Figure 4. Quantitative MRI maps in the remyelination phase, on day 38. Relaxation time constant map of RAFF4 (A), magnetization transfer ratio, MTR (B), T1sat (C), mean diffusivity, MD (D), fractional anisotropy, FA (E), axial diffusivity, AD (F), radial diffusivity, RD (G), T2w image with the lesion (H) and a representative example of ROIs for analyzing lesion on a grayscale RAFF4 map (I). White arrow points to the lesion in the corpus callosum.
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.
