Application of spectral computed tomography in diagnosis of liver and gallbladder diseases

Medical College of Shihezi University

摘要

摘要: 能谱CT成像是宝石探头和强大的计算机后处理技术的完美结合,是对传统CT的一次技术革命。对能谱CT在肝脏、胆囊疾病中的诊断应用作一综述。总结了能谱CT的单能量图像、能谱曲线、物质分离与定量以及有效原子序数等技术在肝胆疾病诊断及鉴别方面的应用价值,并分析其在发现微小病灶、低剂量、判断同源性的优势所在。认为能谱CT在肿瘤的早期发现、鉴别及预后中有很多可探寻的方面。

Abstract: Spectral computed tomography (CT) is a perfect combination of diamond probe and strong computer processing technology and a technological revolution of traditional CT.This article reviews the application of spectral CT in the diagnosis of liver and gallbladder diseases.It summarizes the application value of monochromatic spectral CT imaging, spectral curve, material separation and quantitation, and effective atomic number in the diagnosis and differentiation of liver and gallbladder diseases and analyze the advantages of energy spectrum in identification of small lesions, low dose, and judgment of homology.It is pointed out that the application of spectral CT can be further explored in the aspects of early identification, differentiation, and prognosis of tumors.
