Fig. 2. Comparison between US and MRI atlases of the fetal brain.

Fig. 2

ac, Age-matched templates shown at two axial views: level of the ventricles (a) and level of the thalami (b), and one coronal view (c). Structures colocalize in both modalities, but US templates showed sharper tissue boundaries in the subcortical grey matter areas (red arrows). Blue arrows indicate possible white matter fibre bundles in the US atlas, which are not visible in the MRI atlas. Note that the contrast of the US atlas has been edited to highlight the key structures.
