Assessing cerebrovascular reactivity by the pattern of response to progressive hypercapnia
Sign Up to like & getrecommendations! Published in 2017 at "Human Brain Mapping"
DOI: 10.1002/hbm.23598
Abstract: Cerebral blood flow responds to a carbon dioxide challenge, and is often assessed as cerebrovascular reactivity, assuming a linear response over a limited stimulus range or a sigmoidal response over a wider range. However, these… read more here.

DOI: 10.1002/jmri.27647
Abstract: It is a widely acknowledged clinical challenge that for patients with symptomatic atherosclerotic and nonatherosclerotic intracranial steno-occlusive disease, the rates of high 2-year ischemic stroke occurrence are considerable. In response to this challenging issue, researchers… read more here.

DOI: 10.1016/j.neuroimage.2019.116365
Abstract: Cerebrovascular reactivity (CVR) mapping using CO2-inhalation can provide important insight into vascular health. At present, blood-oxygenation-level-dependent (BOLD) MRI acquisition is the most commonly used CVR method due to its high sensitivity, high spatial resolution, and… read more here.
