Dual-energy computed tomography (CT) has the potential to improve detection of abnormalities and increase diagnostic confidence in the evaluation of a variety of neurologic conditions by using different x-ray energy-dependent absorption behaviors of different materials. This article reviews the virtual monochromatic imaging applications of dual-energy CT, particularly material decomposition algorithms to improve lesion conspicuity, define lesion-normal tissue interface using different reconstruction techniques, and discuss miscellaneous emerging applications of dual-energy CT for neuroimaging, with an emphasis on their potential clinical utility.
双能量计算机断层扫描（CT）有潜力通过利用不同材料对X射线能量依赖性吸收行为，来改善异常的检测并提高对各种神经系统疾病评估的诊断信心。本文综述了双能量CT的虚拟单色成像应用，特别是通过材料分解算法来提高病变的显见度，使用不同的重建技术定义病变与正常组织的界面，并讨论双能量CT在神经成像方面的其他新兴应用，重点是它们潜在的临床效用。
