This study validates the use of VASO-MRI for quantitative measurement of cerebral blood volume in unit of ml blood in 100 ml brain. We measured CBV values using PET and VASO-MRI on the same subjects and compared them. The results showed that VASO-MRI provides quantitative and accurate estimations of CBV values in the human brain. Our data also demonstrated that VASO CBV has a higher SNR compared to the PET technique in addition to providing a higher spatial resolution.
