Cerebrovascular reactivity (CVR) can give insight into the cerebrovascular function. CVR can be estimated by measuring a blood‐oxygen‐level‐dependent (BOLD) response combined with breath‐holding (BH). The reproducibility of this technique has been addressed and existing studies have focused on short‐term reproducibility using a 3 T magnetic resonance imaging (MRI) system. However, little is known...
Background
Whole‐brain global cerebral blood flow (CBF) determined by MRI techniques, calculated using total CBF (TCBF) from phase‐contrast MRI (PC‐MRI), and brain parenchyma volume (BPV) from T1‐weighted image, have become increasingly popular in many applications.
Purpose/Hypothesis
To determine if MRI‐based measurements of whole‐brain global CBF data obtained across different field strengths...
