Respiration Can Trigger Cerebrovascular Reactivity: A Novel Method to Quantify Cerebrovascular Resistance Dynamics Using Real‐Time Phase‐Contrast <scp>MRI</scp>
This gas-free RT-PC approach using the ICA-to-ECA flow ratio provides a stable and reproducible index of respiration-driven CRD, enabling isolation of cerebrovascular resistance modulation from cardiac effects and supporting its potential role in the development of faster and more accessible CVR assessment strategies.
