We compared stable xenon enhanced X-ray computed tomography (Xe-CT) with Technetium-99m ethylsteinate dimer single-photon emission computed tomography (ECD-SPECT) in 12 patients. We evaluated the cerebral blood flow (CBF) values in the territory of the anterior, middle and posterior cerebral artery, and in the thalamus. The CBF values were higher in ECD-SPECT than in Xe-CT except for the values of the thalamus. The posterior cerebral artery territory showed a lower correlation and the thalamus had no correlation between two methods. We discussed causes of these differences.
我们对12例患者的稳定氙增强X射线计算机断层扫描（Xe-CT）与锝-99m依替膦酸盐二聚体单光子发射计算机断层扫描（ECD-SPECT）进行了比较。我们评估了大脑前、中、后动脉供血区域以及丘脑的脑血流量（CBF）值。除丘脑外，ECD-SPECT的CBF值高于Xe-CT。大脑后动脉供血区域在两种方法之间的相关性较低，丘脑在两种方法之间无相关性。我们讨论了这些差异的原因。
