Magnetic Resonance Imaging and Computed Tomography of the Hind-Brain and Upper Cervical Cord: Normal Variation and the Chiari Malformations
Precise imaging of the neuraxis in the region of the craniocervical junction is a reliable practical routine using computed myelography and magnetic resonance imaging (MRI). Morphological features, including variation in the flexed and extended positions, CSF bulk flow, abnormalities in tissue density or signal-reflecting pathological changes in brain and the cord substance and any abnormal permeability and structure of the neuraxis resulting in accumulation of fluid in communication with the extracellular spaces can be outlined.
