Sonographic measurement of the width of the spinal canal

Sonographic evaluation of the width of spinal canal information received, concerning accuracy and especially quantity of CT or myelography is inferior compared to. The advantage of sonography is the lacking of X-ray exposure, the non-invasive procedure and the low cost of us apparat and operational time. For these reasons sonography is favoured as a screening method in detecting spinal canal stenosis in a group whose handicap was largely occupational or Sport-related. (orig.)
