Abstract

　We analyzed changes in apparent diffusion coefficient (ADC) during the cardiac cycle of the brain using bulk-motion-compensated diffusion imaging. ADC changes during the cardiac cycle were predominantly caused by water molecule fluctuations due to brain pulsation rather than the bulk motion of the brain parenchyma.
