摘要
近年来,肺癌、慢性阻塞性肺疾病(COPD)、尘肺等肺部疾病发病率逐年攀升,已成为非常突出的公共医疗卫生问题。肺是以空腔为结构主体的器官,其最主要的功能是气体交换;因此,发展能对肺部气体交换功能进行无创、可视和实时成像的技术至关重要。本文围绕一种新的肺部影像学方法———超极化气体MRI进行综述。
Pulmonary diseases, such as lung cancer, chronic obstructive pulmonary disease （COPD） and pneumoconiosis, are keeping increased in the recent decades, resulting in a significant issue of public health. The structure of the lung is dominated by cavities, and the essential function of the lung is gas exchange. Therefore, an imaging modality, which has the capability to noninvasively visualize the gas exchange in real time, is extremely important to be developed. The progresses of hyperpolarized gas MRI as a cutting-edge pulmonary imaging technique were reviewed in this paper.
