Imaging plays a significant role in radiation therapy. Improvements in treatment delivery require sophisticated imaging technologies to define tumor volume accurately. Magnetic resonance imaging scans can provide morphological and functional information and are increasingly being used in imaging for radiation therapy; however, for lung cancer, most protocols are based on breath-hold imaging and noncompliance to breath-hold maneuver can lead to significant artifacts. For patients presenting for lung cancer radiation therapy, maintaining a breath hold can be impossible. This paper describes a completely free-breathing lung magnetic resonance imaging protocol for use in radiation therapy for lung cancer.
成像在放射治疗中起着重要作用。治疗技术的改进需要先进的成像技术来精确界定肿瘤体积。磁共振成像扫描能够提供形态学和功能信息，并且越来越多地用于放射治疗成像；然而，对于肺癌来说，大多数方案基于屏气成像，而不遵守屏气动作会导致明显的伪影。对于接受肺癌放射治疗的患者而言，保持屏气可能是不可能的。本文描述了一种用于肺癌放射治疗的完全自由呼吸的肺部磁共振成像方案。
