Overview
MRI is the diagnostic neuroimaging study of choice especially for older children and is preferred over CT scan. The diagnostic yield of MRI depends upon the type of CP (mixed > quadriplegic > hemiplegic > diplegic > ataxic > dyskinetic) and the timing of birth.
MRI
- MRI is the diagnostic neuroimaging study of choice especially for older children.[1][2][3][4]
- MRI is preferred over CT due to
- Higher diagnostic yield
- Role in finding out the etiology and timing of insult
- The diagnostic yield of MRI depends upon:
- The type of CP (mixed > quadriplegic > hemiplegic > diplegic > ataxic > dyskinetic)
- Timing of birth (scans are more often abnormal in preterm compared with term infants)
- MRI findings in patients with CP include:
- Hypoxic-ischemic lesions (eg, periventricular leukomalacia [PVL])
- Cortical malformations
- Lesions of the basal ganglia
- MRI may show:
- Myelination for a given age
- A tethered spinal cord
- MRI is found to be abnormal in 90% of children with cerebral palsy.[5]
- MRI has an important role in predicting neurodevelopmental outcomes in preterm infants.[6]
- MRI may be normal in cerebral palsy- does not exclude the diagnosis and require exclusion of metabolic and genetic etiologies
