摘要： Z maps combined with a standardized stimulus in the form of a targeted arterial partial pressures of carbon dioxide provide suprisingly enhanced images for the assessment of pathological CVR. For example, the z-map assessment of patients with known steno-occlusive diseases of the cervico-cerebral vasculature showed an enhanced resolution of the presence, localization, and severity of the pathological CVR. Z-map have been found to be useful to reduce the confounding effects of test-to-test, subject-to-subject, and platform-to-platform variability for comparison of CVR images showing the importance of combining this analysis with the standardized stimulus.

摘要： An algorithm including program code for analyzing a specific portion of the vasoactive response to the vasoactive stimulus corresponding to a to sub-range of increments and/or decrements of stimuli within the full range of the vasoactive stimulus, the sub-range characterized in that is more sensitive to identifying reductions in vascular reactivity in the ROI.
