The MRI manifestation of brain injury in preterm infants is to determine changes such as brain hemorrhage, brain lesions, and other changes. The MRI manifestation mainly depends on the scope of involvement of brain injury in preterm infants, dividing the degree of injury and the duration of the decision.
The main areas of change are thalamus basal ganglia + internal capsule posterior limb involvement, watershed and extensive cortical white matter injury, focal-multifocal microscopic white matter injury, and extensive whole brain injury, and so on.
The lesions may be found to be particularly point-like, varying in number, sometimes present in lines or clusters, out of severe cerebral edema (brain swelling), poorly differentiated gray and white matter, long T1 and T2 signals on MRI (low signal on T1WI, high signal on T2WI), extensive high signal on DWI, and a wide range of other manifestations to determine brain injury.
When preterm infants are born with conditions such as hypoxia or ischemia, they must be treated aggressively to prevent other complications caused by this condition.
