Cardiac cycle-induced EPI time series fluctuations in the brain: Their temporal shifts, inflow effects and T(2)(∗) fluctuations
The cardiac-induced arterial pressure wave causes changes in cerebral blood flow velocities and volumes that affect the signals in echo-planar imaging (EPI). Using single-echo EPI time series data, acquired fast enough to unalias the cardiac frequency, we found that the cardiac cycle-induced signal...
