Premature infants were allocated to the case group (<jats:italic>n<\/jats:italic> = 15) and NON IVH (<jats:italic>n<\/jats:italic> = 35). The T1, T2, PD values, and brain volume were obtained by synthetic MRI.

There were significant differences also in PD. The brain volume in many parts were also significantly reduced, which was best illustrated in gray matter (GM), cerebrospinal fluid and intracranial volume, and brain parenchymal fraction (BPF) (each <jats:italic>p<\/jats:italic> &amp;lt; 0.001, <jats:italic>t<\/jats:italic> = \u22125.232 to 4.596).
