Diffusion tensor imaging demonstrated radiologic differences between diplegic and quadriplegic cerebral palsy

► Radiologic differences between quadriplegic CP and diplegic CP. ► Significant FA difference of distal extremities between diplegia and quadriplegia. ► Significant FA difference of lower extremity between diplegia and normal controls. ► No significant FA difference of the upper extremity between diplegia and normal controls. ► DTI results in quadriplegia and diplegia coincided with the typical clinical patterns.
