摘要
胸部CT是目前最常用的肺结节良恶性鉴别的影像学方法,但其存在辐射负担;而MRI没有辐射风险,可以多参数成像,并已被广泛应用于全身。但MRI在肺结节的应用受到一些限制,原因如肺的低质子信号导致的低信噪比、肺与临近软组织界面的磁化率伪影和心肺运动伪影。随着MRI抗运动伪影技术、超短回波时间序列、功能磁共振和影像组学/人工智能技术的不断发展,MRI在肺结节良恶性鉴别方面具有极大的潜力。本文综述了MRI在肺结节良恶性鉴别定性和定量方面的应用价值,MRI可以作为CT、PET/CT鉴别肺结节良恶性的很好的补充检查手段。
Chest CT is the most commonly used imaging method for the differentiation of benign and malignant pulmonary nodules currently,but it exists radiation burden.MRI has no radiation risk,and it can be multi-parametric imaging and has been widely used throughout the whole body.However,the application of MRI in pulmonary nodules is somewhat limited because of the reason such as low signal-to-noise ratio due to the low proton signal of the lung,susceptibility artifacts at the interface between the lung and adjacent soft tissues,and cardiopulmonary motion artifacts.Following with the constant development of MRI anti-motion artifact techniques,ultrashort echo time sequences,functional MRI and radiomics/artificial intelligence techniques,MRI shows huge potential for the differentiation of benign and malignant pulmonary nodules.This article reviews the application value of MRI in the qualitative and quantitative differentiation of benign and malignant pulmonary nodules,MRI can be used as a good complementary examination tools on the basis of CT and PET/CT examination for the differentiation of benign and malignant pulmonary nodules.
