[Spinal stenosis].

Space conditions in the spine canal play the decisive role in the origin of neurological difficulties connected with pressure on the spinal cord and its radices. For the diagnosis of spinal stenosis the dimensions of the spine canal are of importance: sagital, interpedicular, interarticular and the width of lateral recessus of the spine canal. The diagnostics of spinal stenosis is based on the anterior-posterior and lateral picture of the spine, CT examination and contrast examination of the spine canal--myeloradiculography. CT is included in the diagnostic algorhythm on the 2nd place after picture of the spine in classical projections. The anvantage of CT in its non-invasiveness, illustration without projection distortion and high sensitivity and specificity of the examination. Myeloradiculography is indicated for cases of uncertain findings with CT or discrepancy of the CT picture and clinical condition. It may be presumed that in the near future the CT examination will be required in the diagnosis of spine stenosis more frequently by the physicians.
