Figure 2. — Representative MR images for the CMRO₂ measurement. (a) TRUST MRI for the measurement of global Y_v. Red arrow indicates the SSS. The subtraction of control and labeled images yielded pure blood signal. (b) The fitting of the signal as a function of effective TE can generate an estimation of blood T₂. Data from four different respiratory states are shown. (c) Phase contrast MRI for the measurement of CBF. Darker color indicates a greater flow velocity.

CMRO₂: cerebral metabolic rate of oxygen; TRUST : T₂-Relaxation-Under-Spin Tagging; SSS: superior sagittal sinus.
