Imaging plays an important role in elucidating many of the aetiologies of cerebral palsy in children. Magnetic resonance imaging is a particularly powerful tool in the evaluation of the causes of cerebral palsy, both in the acute and chronic phases. We will review the role of MRI in assessment of various aetiologies contributing to cerebral palsies. These categories include congenital malformations, intracranial haemorrhage, hypoxic-ischaemic injury, periventricular leukomalacia and white matter injury of prematurity, perinatal ischaemic stroke, and a number of other neonatal encephalopathies. In this chapter, we will review the utility of MRI in the evaluation of cerebral palsy in the young child.
