Unlike any other organ, imaging of lungs with magnetic resonance faces unique challenges owing to the complex microstructure and presence of gas-tissue interfaces. With the evolution of faster and stronger gradient systems leading to ultrafast imaging with ultrashort echo times, pulmonary magnetic resonance imaging (MRI) is no longer considered a technical challenge. In terms of functional evaluation, lungs are also associated with a unique function, viz. ventilation. Evaluation of ventilation is feasible with MRI either by using hyperpolarized noble gases or in an indirect fashion by performing oxygen-enhanced MRI. This chapter will provide an overview of these two methods.
与其他任何器官不同，由于肺部复杂的微观结构以及气体-组织界面的存在，肺部的磁共振成像面临着独特的挑战。随着更快、更强的梯度系统的发展，实现了具有超短回波时间的超快成像，肺部磁共振成像（MRI）不再被视为一项技术难题。在功能评估方面，肺部还具有独特的功能，即通气功能。通过使用超极化惰性气体或通过进行氧增强MRI以间接方式，利用MRI评估通气功能是可行的。本章将概述这两种方法。
