Assessment of Brain Perfusion and Vascular Compliance with Magnetic Resonance Imaging
… perfusion is relatively static index of brain vascular function, vascular compliance represents the dynamic ability of arteries to dilate or retract in response to blood pressure alternations. An artery vessel with high compliance can better buffer the pulsatility of blood flow, thereby …

Expanding the role of functional mri in rehabilitation research
Functional magnetic resonance imaging (fMRI) based on blood oxygenation level dependent (BOLD) contrast has become a universal methodology in functional neuroimaging. However, the BOLD signal consists of a mix of physiological parameters and has relatively poor reproducibility. As fMRI becomes a …
