Roentgenmorphological muscle changes in anterior horn cell lesions.

The author examined muscles in the extremities of 42 poliomyelitis patients using a special roentgenological technique. This method made it possible to objectively determine the size of the muscles in the soft tissues of the extremities. The volume and distribution of the increased amounts of fatty tissue in the muscle and the volume of normal muscle tissue led to draw conclusions regarding the histological state of the muscle. Roentgenmorphological changes are closely linked to muscle dysfunction. Roentgenological examination of the soft tissue provides a useful supplement to a muscle biopsy and to electromyographic examinations and is of value for the rehabilitation of the patients.
