Radiology of the stenotic lumbar canal

The main objective of imaging diagnostics in the study of the stenotic lumbar canal is that of revealing the presence of any contents/container conflict, of determining its site, extent, extension and, when possible, its etiopathogenesis. At present, CT and MRI constitute the most sensitive and specific methods, available necessarily preceded by a conventional radiological examination. Clinical assessment influences the choice of the method to use, whether alone or in association with others, as well as the method used to carry out the investigation; if we add all of this to correct technical execution, the radiological examination will provide a considerable amount of data.
