MRI can demonstrate and differentiate the various insults and anomalies that can be responsible for cerebral palsy. Recent advances have resulted in techniques and sequences that allow prompt detection of cytotoxic edema and evaluation of brain perfusion. MRI precisely demonstrates the various patterns of injury, distinguishing insults owing to profound asphyxia, partial prolonged asphyxia, and mixed partial prolonged and profound asphyxia. Infants and children can be studied with MRI, and ultrafast MRI permits evaluation of the fetal central nervous system. In the fetus, the cause of ventriculomegaly can be determined, such as cerebrospinal fluid flow obstruction, brain malformation, or brain destruction with or without hemorrhage. Results from fetal MRI have led to better understanding of many brain abnormalities.
磁共振成像（MRI）能够显示并区分可能导致脑瘫的各种损伤和异常情况。最近的进展带来了一些技术和序列，可实现对细胞毒性水肿的快速检测以及脑灌注的评估。MRI能精确显示各种损伤模式，区分由严重窒息、部分长时间窒息以及部分长时间和严重混合性窒息所导致的损伤。婴儿和儿童都可以接受MRI检查，而超快MRI则能够对胎儿中枢神经系统进行评估。对于胎儿，可以确定脑室扩大的原因，例如脑脊液流动受阻、脑畸形或伴有或不伴有出血的脑破坏。胎儿MRI的结果有助于更好地理解许多脑部异常情况。
