[Sagittal widths of the cervical spinal canal in the computerized tomogram].

The sagittal diameter of cervical spinal canals provided in radiological and anatomical literature cannot be used for the computertomographical diagnostics. Values measured by CT are lower than widths determined by other methods. Resulting from its high sensitivity computertomography detects even slight mineralisations and ossifications that cannot be seen on conventional X-ray pictures. CT is therefore the most suitable X-ray method for the diagnosis of stenosed cervical spinal canals.
