Streamlined-qBOLD is a baseline brain oxygenation measurement technique that has qualitatively shown promising results for the early identification of the ischaemic penumbra. Here regional definitions of tissue outcome are used to further investigate the application of this technique in acute stroke. Quantitative brain oxygenation parameters are demonstrated to vary between regions with different tissue outcomes.
