This study analyzed multi-shell diffusion MRI on a population of 17 dyslexic children and 18 controls. Advanced models (Diamond & Microstructure Fingerprinting), obtained stronger correlations with children's reading and spelling performance than DTI and showed increased sensitivity.
Figure 2. Sagittal view of a 3D representation of the regions of interest described in this report : arcuate fasciculus (in blue), inferior fronto-occipital fasciculus (in green), inferior cerebellar pedunculus (in yellow), middle cerebellar pedunculus (in orange) and superior cerebellar pedunculus (in red).
Table 2. Statistically significant differences between the control (C) and dyslexic (D) populations per region and per metric. The models from which the metrics are obtained are mentioned : Diffusion Tensor Imaging (DTI), Microstructure Fingerprinting (MF) or Diamond (DMD). The correlation observed between each metric and the spelling and reading performances in both populations are also provided in the leftmost columns.
