Measuring Relative CBV from the recirculation part of concentration time curve is investigated on rat model. Since the first pass of DSC method is relative fast on rat, more data points could be recruited for CBV quantification in the recirculation part. The results showed better regression lines between MION CBV and recirculation CBV, and therefore the feasibility is proved in this study.
