Asymmetric Spin Echo (ASE) is a popular technique to obtain quantitative estimates of R2’, cerebral venous blood volume (vCBV), and oxygen extraction fraction (OEF) noninvasively in normal subjects. In this study, We demonstrated the feasibility of using Triple-Echo ASE to induce a more stable and accurate vCBV and OEF estimates with no increase in scan time. In addition, this study investigated the role of diffusion in ASE measurements and provided insights into future acquisition approaches.
