Fig. 1.

T1-maps, generated by “SyMRI”, are shown in the upper row. Conventional T1-images are shown in the bottom row. The left column shows the quantitative T1-map and the conventional image of a term-born neonate. The right column shows the quantitative T1-map and the conventional T1-image of a former premature infant. T1-relaxation constants are represented by the colored bar. The bluish signal in the posterior limb of the internal capsule in the term-born infant indicates myelin (arrows). The corresponding signal is absent in the premature infant. The color-coding of the tissue in the quantitative maps enables an easier distinction between preterm and term-born neonates compared with conventional images
