SE T1-weighted midsagittal image (TR, 560; TE, 15) from which measurements of the AP diameter of the whole pons (black arrow), basis (white broken arrow), tegmentum (white arrow), and corpus callosal length (white dotted arrow) were obtained.

A, Whole pontine diameters in the PVL group and control group plotted with respect to age. The whole pontine diameter in the PVL group is smaller than in the control group. B, Basis diameters in the PVL group and control group plotted with respect to age. The basis diameter in the PVL group is smaller than in the control group. C, Tegmentum diameters in the PVL group and control group plotted with respect to age. Tegmentum diameter in the PVL group was smaller than in the control group. D, Corpus callosal lengths in the PVL group and control group plotted with respect to age. Corpus callosal length in the PVL group was smaller than in the control group.

A, Relationship between each age group and mean of whole pontine diameter (with 1 SD). In each age group, the whole pontine diameter in the PVL group is significantly smaller than in the control group. B, Relationship between each age group and mean basis diameter (with 1 SD). In the 0-, 1-, and 3-year age groups, basis diameter in the PVL group was significantly smaller than in the control group. C, Relationship between each age group and mean tegmentum diameter (with 1 SD). In the 1-, 2-, and 3-year age groups, tegmentum diameter in the PVL group was significantly smaller than in the control group. D, Relationship between each age group and mean corpus callosal length (with 1 SD). In each age group, corpus callosal length in the PVL group was significantly smaller than in the control group.

Correlation between whole pontine diameter and corpus callosal length in the PVL group (A) and the control group (B). In the PVL group (A), the correlation coefficient was 0.52, which was statistically significant (P < .001). The correlation coefficient in the control group (B) was 0.63, which was also statistically significant (P < .001).
