Figure 2 Receiver operating characteristic curve showing the incremental benefit of each of the discussed modalities Receiver operating characteristic curve showing the incremental benefit of each of the discussed modalities Measure of relative sensitivity and specificity of the different techniques described; studies are as listed in figure 1. Increased CSF pressure elevations in response to arterial pulsations16 are labeled CSF puls hyper. Results from studies in columns 4,18 5,19 6,20 and 1117 of figure 1 were combined to provide a pooled assessment of Ro. Results from studies in columns 7,26 8,28 and 927 were combined to provide a pooled assessment of elevated CSF flow by MRI. Results from studies in columns 231 and 1017 were combined to provide a pooled assessment of the CSF tap test. ELD = external lumbar drainage. John J. Halperin et al.
