Recently, the total cerebral blood flow (tCBF) and
venous oxygen saturation (SvO2) levels are measured
noninvasively with the MRI approaches to quantify the
global cerebral metabolic rate of oxygen (CMRO2). In
this research, the ROI analysis with the cardiac gating
sequence is applied in healthy subjects to demonstrate
the impact of fluctuated tCBF induced by cardiac
pulsation on the global CMRO2 measurement.
