摘要:

与传统计算机断层扫描(computed tomography,CT)成像不同,宝石能谱CT最显著的特征就是提供了多种定量分析方法与多参数成像的综合诊断模式,如单能量图像、能谱曲线、物质分离图像和有效原子序数等,它为疾病的早期发现、定量评估和准确诊断提供了一个新颖的工具,也为临床和科研提供了一个全新的平台。了解和熟悉能谱CT的概念和成像原理,对于影像科医生乃至临床医生都是非常必要的。

Abstract:

The most prominent advantages of gemstone spectral computed tomography(CT) over conventional CT are its set of quantitative analysis and multi-parameter images, such as monochromatic images, spectral curve, material decomposition images and effective atomic number. Spectral CT provides not only an original tool for early diagnosis of diseases, quantitive evaluation and accurate diagnosis but also a novel platform for clinical and research. It is important for radiologists and clinicians to understand and be familiar with the concept and principle of spectral CT
