The studies found that although MRI findings were often related to future problems they did not always predict learning and behavior problems. The authors suggested that thorough tests of neurological functioning were probably more useful. Pediatric Radiology . Skranes, Vik, Nilsen et al. Myelination refers to the insulation of the nerve fibers with a fatty substance known as myelin.
Myelin helps conduct nerve impulses.
Ventricular malformation and enlargement usually indicates that parts of the surrounding brain tissue have died and that the ventricles have enlarged to fill in the spaces. Most of the children with abnormal MRIs at age 1 continued to have abnormal MRIs at age 6. 12 out of 13 children with these findings showed continued signs of PVL at age 6. Abnormalities in the central occipital white matter alone had normalized in two children and persisted as delayed myelination in 3 children at age 6. The 20 children were then tested for IQ, motor, and perceptual functioning.
