title: Videodensitometry of cerebrospinal fluid pulsations.
abstract: Roentgen videodensitometry (RVD) during myelography is described in 13 patients with a variety of intraspinal lesions. Abnormalities in the RVD tracing are discussed and correlated with the type of spinal canal obstruction. Intramedullary, intradural and extradural processes may be differentiated by RVD.
