能谱CT成像在肺癌诊断中的应用研究进展

能谱成像是近年来CT成像领域的一项新技术, 具有多参数、定量分析等成像特点, 其主要技术包括物质分离、单能量图像、能谱曲线和有效原子序数测定。通过多种参数和分析工具的综合应用, 能谱CT能够客观反映病变的组织特征, 对确定病变的组织来源和范围、鉴别诊断等方面具有潜在价值。其在肺癌的筛查、肺结节的良恶性判定等方面的研究中也取得了初步成果, 笔者就能谱CT的主要技术及其在肺癌诊断中的应用作一综述。

Research progress of spectral imaging in the diagnosis of lung cancer

Spectral imaging is a new technique in the field of CT imaging in recent years, with many parameters, quantitative analysis of imaging characteristics, the main technology including material separation, single energy image, can measure the spectrum curve and the effective atomic number.Through the comprehensive application of various parameters and analysis tools, spectrum imaging can reflect the characteristics of lesions, and has potential value to determine the source and scope, differential diagnosis etc..The screening of lung cancer, the identifying of benign and malignant pulmonary nodules and other aspects of the study also achieved initial results.This article focuses on the spectrum technology and its application in diagnosis of lung cancer.
