Over the last few decades, advances in radiation therapy technology have markedly improved radiation delivery. Advancements in treatment planning with the development of image-guided radiotherapy and techniques such as proton therapy, allow precise delivery of high doses of radiation conformed to the tumor. These advancements result in improved locoregional control while reducing radiation dose to surrounding normal tissue. The radiologic manifestations of these techniques can differ from radiation induced lung disease seen with traditional radiation therapy. Awareness of these radiologic manifestations and correlation with radiation treatment plans are important to differentiate expected radiation induced lung injury from recurrence, infection and drug toxicity.
在过去的几十年中，放射治疗技术的进步显著改善了放射治疗的实施。随着图像引导放射治疗和质子治疗等技术的发展，治疗计划的改进使得能够精确地将高剂量的放射治疗送达肿瘤。这些进步提高了局部区域控制率，同时减少了对周围正常组织的辐射剂量。与传统放射治疗中观察到的放射性肺疾病相比，这些技术的放射学表现有所不同。了解这些放射学表现，并与放射治疗计划进行相关性分析，对于区分预期的放射性肺损伤与复发、感染和药物毒性非常重要。
