摘要 三维动脉自旋标记(three-dimensional arterial spin labeling,3D-ASL)技术是一种无需注入外源性对比剂的磁共振灌注成像技术。与普通的二维动脉自旋标记(arterial spinlabeling,ASL)相比,3D-ASL具有更高的信噪比、更快的采集速度。3D-ASL的一个重要扫描参数是标记后延迟时间,对于这个参数的选择会影响到测得脑血流量(cerebral blood flow,CBF)的准确性。因此,针对不同人群、根据不同目的选取合适的参数非常重要。3D-ASL可以很好地反映脑血流灌注情况,在缺血性脑梗死的灌注评估中有重要应用价值。3D-ASL不仅可以帮助探查闭塞血管、评估缺血半暗带、预测出血转化,还有助于调整治疗方法及判断患者预后。 Three-dimensional arterial spin labeling is a kind of magnetic resonance perfusion weighted imaging technique, which is no need to inject exogenous contrast agents. Compared with the normal two-demensional ASL, there are many superiorities in 3 D-ASL, such as the higher signal-to-noise ratio and the faster acquisition speed. One of the scanning parameters of3 D-ASL is post-labeling delay time. The selection of this parameter will affect the accuracy of CBF measurement. Therefore, it is very important to select suitable parameters according to different purpose or different population. 3 D-ASL could reflect the cerebral blood perfusion very well, so there is great value of application in the perfusion assessment of ischemic stroke. 3 D-ASL can not only help to explore occluded vessels, evaluate ischemic penumbra, predict hemorrhage transformation, but also help to adjust treatment methods and judge prognosis of patients.
