Brain temperature measured by proton magnetic resonance spectroscopy evaluates as a parameter of cerebral hemodynamic impairment in patients with chronic major cerebral artery steno-occlusive disease : Comparison with positron emission tomography

本研究的目的是评估脑血流动力学损害的测量脑温度（BT）使用质子磁共振波谱与正电子发射断层扫描相比，在慢性主要脑动脉狭窄闭塞性疾病的患者。患侧大脑半球的▲BT（▲BT）之间存在显著相关性。对侧大脑半球的BT）和脑血容量（CBV）比（受累大脑半球的CBV与对侧大脑半球的CBV之比）。▲BT与氧提取分数比呈显著正相关。

The aim of this study is to estimate cerebral hemodynamic impairment by measurement of brain temperature(BT) using proton magnetic resonance spectroscopy compared with positron emission tomography in patient with chronic major cerebral artery steno-occlusive disease. There was significant correlation between▲BT(▲BT in the affected cerebral hemisphere. BT in the contralateral cerebral hemisphere) and cerebral blood volume(CBV) ratio(ratio of CBV in the affected cerebral hemisphere to that in the contralateral cerebral hemisphere). There was a significant correlation between▲BT and oxygen extraction fraction ratio.
