Proton magnetic resonance imaging (MRI) has recently emerged as a clinical tool to image the lungs. This paper outlines the current technical aspects of MRI pulse sequences, radiofrequency (RF) coils and MRI system requirements needed for imaging the pulmonary parenchyma and vasculature. Lung MRI techniques are presented as a "technical toolkit", from which MR protocols will be composed in the subsequent papers for comprehensive imaging of lung disease and function (parts 2 and 3). This paper is pitched at MR scientists, technicians and radiologists who are interested in understanding and establishing lung MRI methods. Images from a 1.5 T scanner are used for illustration of the sequences and methods that are highlighted. Main Messages • Outline of the hardware and pulse sequence requirements for proton lung MRI • Overview of pulse sequences for lung parenchyma, vascular and functional imaging with protons • Demonstration of the pulse-sequence building blocks for clinical lung MRI protocols.
质子磁共振成像（MRI）最近已成为一种临床工具，可用于肺部成像。本文概述了用于肺部实质和血管成像的 MRI 脉冲序列、射频（RF）线圈和 MRI 系统要求的当前技术方面。肺部 MRI 技术被呈现为一个“技术工具包”，后续的论文将根据这些技术组成用于全面成像肺部疾病和功能的 MR 协议（第 2 部分和第 3 部分）。本文面向对理解和建立肺部 MRI 方法感兴趣的磁共振科学家、技术人员和放射科医生。使用 1.5T 扫描仪的图像来说明突出显示的序列和方法。主要信息 • 质子肺部 MRI 的硬件和脉冲序列要求概述 • 用于肺部实质、血管和功能成像的脉冲序列概述 • 临床肺部 MRI 协议中脉冲序列构建模块的演示
