摘　　要：多排螺旋CT技术的广泛应用及计算机后处理技术的不断发展,使能谱CT成像从理论走向实践。与常规多排CT相比,能谱CT及时实现了包括单能量图像、能谱曲线、基物质图像及相应基物质的定量分析、有效原子序数等多参数成像,为疾病的早期发现、定性甚至定量诊断提供可靠依据,为临床实践和科研提供更为广阔的发展空间。Advances in multi-detector technology and computer processing technology have made spectral CT imaging possible. Compared with conventional multi-detector CT, spectral CT have realized multi-parameter imaging, including monochromatic imaging, spectral curve, basis pair for material-decomposition images in quantitative analysis and effective atomic number. These imaging technologies provide reliable information to diagnose disease earlier and more accurately. Spectral CT is a promising technique with clinical application potential.
