This study aims to explore the clinical value of the absolute quantitative dynamic susceptibility contrast cerebral perfusion-weighted imaging using Self-Calibrated EPI sequence (SCALE-PWI) in patients with ischemic stroke. SCALE-PWI could provide reliable quantitative measurement of cerebral blood flow (CBF), cerebral blood volume and mean transit time in a quite short scan time of 2:14 mins. Results suggest the CBF values in infarct core are significantly lower than the values in ischemic penumbra. In conclusion, the SCALE-PWI could provide quantitative hemodynamic information in a quite short scan time, thus may serve as a guide for tissue-based decision making and personalized treatment planning in acute stroke.
