A practical modification to a resting state fMRI protocol for improved characterization of cerebrovascular function
Stickland, Rachael C.; Zvolanek, Kristina M.; Moia, Stefano; Ayyagari, Apoorva; Caballero-Gaudes, César; Bright, Molly G. (NeuroImage, 2021)Cerebrovascular reactivity (CVR), defined here as the Blood Oxygenation Level Dependent (BOLD) response to a CO 2 pressure change, is a useful metric of cerebrovascular function. Both the amplitude and the timing (hemo- ... -
Comparing end-tidal CO 2 , respiration volume per time (RVT), and average gray matter signal for mapping cerebrovascular reactivity amplitude and delay with breath-hold task BOLD fMRI
Zvolanek, Kristina M.; Moia, Stefano; Dean, Joshua N.; Stickland, Rachael C.; Caballero-Gaudes, César; Bright, Molly G. (ELSEVIER, 2023)Cerebrovascular reactivity (CVR), defined as the cerebral blood flow response to a vasoactive stimulus, is an imag- ing biomarker with demonstrated utility in a range of diseases and in typical development and aging ... -
Lag-Optimized Blood Oxygenation Level Dependent Cerebrovascular Reactivity Estimates Derived From Breathing Task Data Have a Stronger Relationship With Baseline Cerebral Blood Flow
Stickland, Rachael C.; Zvolanek, Kristina M.; Moia, Stefano; Caballero-Gaudes, César; G. Bright, Molly (Frontiers, 2022)Cerebrovascular reactivity (CVR), an important indicator of cerebrovascular health, is commonly studied with the Blood Oxygenation Level Dependent functional MRI (BOLD-fMRI) response to a vasoactive stimulus. Theoretical ...
