查询词典 myelin

The signal intensity characteristic of MRI associated with brain myelinization is helpful to differentiate the normal and abnormal brain maturation.Also,T1WI is much more useful in the detection of immature myelin and in monitoring of normal brain development in the first 6 months of life.On the other hand,T2WI is more useful after 6 months of life.
