由于血液中Hb在与氧结合成HbO2时磁矩和顺磁性均下降,而去氧后变成dHb,具有顺磁效应可导致血管内外出现非均匀性磁场,使T2*缩短,MR信号减小。因而利用快速梯度扫描序列来观察组织MR信号变化,可以反映血液中dHb与HbO2的比例。当大脑皮层受到生理刺激,局部神经元活动增加使其代谢率增高,局部血管扩张,血流量增加,但在增加...
If your blood oxygen level reads low, your doctor may put you on supplemental oxygen. This therapy provides you with higher amounts of oxygen than are in normal room air, and it can help raise your blood oxygen level. It's usually delivered through a nasal cannula (a small plastic hose ...

当大脑皮层受到生理刺激,局部神经元活动增加使其代谢率增高,局部血管扩张,血流量增加,但在增加程度上有明显差异,局部组织中氧的供应量超过代谢的耗氧量,HbO2相对增加,顺磁性的dHb相对减少,表现为该脑区的T2*MR信号强度相对增加。临床应用:fMRI研究已取得了很大的成绩,目前的研究已不仅停留在用fMRI技术来显示神经活动...
One candidate is deoxyhemoglobin (deoxy-Hb) as an indicator of the oxygen extraction fraction that can be visualized by T2*-based blood oxygen level-dependent (BOLD) imaging. METHODS: We analyzed data from 32 patients with acute stroke in the territory of the middle cerebral artery. MRI ...
