Using a 2-variable method in radionuclide shuntography to predict shunt patency.

摘要: Object Radionuclide shuntography interpretation is uncertain when the tracer fails to enter ventricles but quickly drains distally or enters takes longer than 15 minutes drain distally. The purpose of this study was aid in clinical a variety results and determine applicability different patient populations. Methods 259 shuntograms were reviewed. Chi-square analysis performed evaluate relationship between variables results. Two-by-two binary classification analyses sensitivity, specificity, positive predictive value, negative value for 4 combinatorial types based on 2 variables: ventricular entry distal drainage. Results Median age 19 years, 51% patients male. most common presentation undergoing was...
