Quantitative radioisotope ventriculography: a comparative study.

This report deals with quantitative techniques of isotopic ventriculography. In a series of 25 hydrocephalic patients, several parameters have been studied. An effort has been made to determine which of them is more significant when compared with the clinical course of the patients. Confidence intervals for population mean of this parameter were calculated. The results can be of clinical use in deciding if the clinical course of a hydrocephalic patient is arrested or progressing, and in assessing the advisability of surgical intervention.
