能谱CT在肺癌中的应用进展

Research Progress of Spectral CT in Lung Cancer

常规CT是评估肺癌的一种重要成像方式,但其成像方式单一。目前,能谱CT的多参数成像技术(如虚拟单能量成像、能谱衰减曲线、物质分解图像和有效原子序数)在提高病灶检测率、肺良、恶性结节鉴别、评估肺癌淋巴结转移、病理分型、疗效及预后等方面有一定价值。本文总结能谱CT成像方法及上述4种技术在肺癌方面的相关研究结果并进行综述。

Conventional CT is an important imaging modality for the evaluation of lung cancer,but it has a single imaging modality.At present,multiparametric imaging techniques of spectral CT(such as virtual monoenergetic imaging,spectral attenuation curves,material decomposition images and material effective atomic number)are valuable in improving the detection rate of lesions,differentiating benign and malignant of lung nodes,assessing lymph node metastasis,pathological staging,efficacy and prognosis of lung cancer.Here,this article summarizes and reviews spectral CT imaging methods and the results of studies related to the above four techniques in lung cancer.
