Abstract
The clinical usefulness of cisternography in selecting patients with presumed normal-pressure hydrocephalus for shunting was investigated in 76 patients. The predictive value of a scale based on combined clinical and computed tomographic criteria was first established, followed by an assessment of the predictive value of cisternography. Predictions based on cisternograms were identical to those of the clinical/computed tomographic scale in 43%, better in 24%, and worse in 33%. Our findings suggest that cisternography does not improve the diagnostic accuracy of combined clinical and computed tomographic criteria in patients with presumed normal-pressure hydrocephalus.
