1 Axial T2-weighted MR images
Axial T2-weighted MR images.A, Image in a 21-month-old girl with grade 0 myelination in the frontal lobe. Axial T2-weighted MR images.A, Image in a 21-month-old girl with grade 0 myelination in the frontal lobe. The subcortical white matter is clearly hyperintense, so not myelinated, in the prerolandic area and along the first and second convolutions bilaterally. Subcortical hyperintensity was also evident in the frontopolar regions.B, Example of grade 2 myelination in the frontal area. A T2 hyperintensity is present along the first and second convolutions, while the prerolandic area is myelinated.C, Example of grade 3 myelination. T2 hyperintensity is no longer evident, and myelination appears complete. Cecilia Parazzini et al. AJNR Am J Neuroradiol 2002;23: ©2002 by American Society of Neuroradiology
