Radionuclide blood levels during cisternography of patients with normal-pressure hydrocephalus or Alzheimer's disease

Abstract
✓ Various diagnostic procedures were compared during investigations of 37 dementia patients undergoing differential study for normal-pressure hydrocephalus or Alzheimer's disease. A diminished radionuclide level in the blood, with abnormal cisternography and pneumoencephalography, provided the most valuable diagnostic evidence of normal-pressure hydrocephalus.
