与传统的基于计算机断层扫描（CT）的模式相比，磁共振引导放射治疗（MRgRT）在放射治疗的图像引导方面具有优势。磁共振（MR）的上级软组织对比度能够在腹部和胸部恶性肿瘤的治疗中改善大体肿瘤和邻近正常组织的可视化。在线自适应功能，加上先进的运动管理的实时跟踪肿瘤，直接允许高精度间/分次内定位。该病例系列的主要目的是描述基于MR的介入治疗，用于定位传统图像引导技术无法良好可视化的靶点。描述了肺、肾、肝和胃目标的腹部和胸部部位，以说明放射治疗中MR引导的技术进步。
Magnetic resonance-guided radiation therapy (MRgRT) offers advantages for image guidance for radiotherapy treatments as compared to conventional computed tomography (CT)-based modalities. The superior soft tissue contrast of magnetic resonance (MR) enables an improved visualization of the gross tumor and adjacent normal tissues in the treatment of abdominal and thoracic malignancies. Online adaptive capabilities, coupled with advanced motion management of real-time tracking of the tumor, directly allow for high-precision inter-/intrafraction localization. The primary aim of this case series is to describe MR-based interventions for localizing targets not well-visualized with conventional image-guided technologies. The abdominal and thoracic sites of the lung, kidney, liver, and gastric targets are described to illustrate the technological advancement of MR-guidance in radiotherapy.
