Quantitative assessment of the reproducibility of functional activation measured with BOLD and MR perfusion imaging: implications for clinical trial design.
BOLD contrast is the most commonly used functional MRI method for studies of brain activity. However, the underlying physiological processes giving rise to measured BOLD signal changes (which include contribution from changes in cerebral blood flow (CBF), cerebral blood volume (CBV) and cerebral met...
