A quantitative estimate of cerebral blood oxygen saturation is of critical importance in the investigation of cerebrovascular disease because of the fact that it could potentially provide information on tissue viability in vivo. In the current study,

Acute hypercapnia simultaneously induces increases in regional cerebral blood volume (rCBV) and the oxygen saturation of cerebral venous blood (Yv). Changes in both physiologic parameters may influence the changes in R2* (ΔR2*) that can be measured

T2*-weighted gradient echo magnetic resonance images of rat brain were obtained dynamically during acute hypoxemic hypoxia to investigate the relations between changes in cerebral blood oxygen saturation(ΔYb), blood hematocrit (Hct), and R2* (ΔR2*)

Increases of vascular extravasations of MR contrast agent have been implicated to be predictive of hemorrhagic transformation in acute stroke patients. However, systemic studies are lacking. In this study, we aim to determine how the increased vascul

The balance between cerebral blood flow (CBF) and oxygen extraction fraction (OEF) is important in determining the status of tissue viability during acute cerebral ischemia 1, 2. After ischemic onset, CBF decreases, accompanied by an increase in OEF

Vascular transfer function (VTF) could potentially provide highly relevant physiological information, particularly in patients with cerebrovascular diseases. In this study, we aim to investigate potential alterations of intracranial VTF in patients w
