摘要

我们开发并评估了一种多平面电影磁共振成像（MRI）工作流程，用于磁共振（MR）引导的在线适应性放射治疗（MRgOART）胃粘膜相关淋巴组织（MALT）淋巴瘤。两名患者使用该工作流程进行了MRgOART，可以实时评估胃运动，并确保在计划目标体积内准确覆盖目标。我们的工作流程可以可视化由呼吸和蠕动引起的复杂胃内运动。总治疗时间临床可接受。所有分数都满足我们的剂量限制。我们的工作流程支持对具有可变形状和运动的目标（如胃MALT淋巴瘤）进行精确的MRgOART递送。

New workflow and motion analysis for gastric mucosa-associated lymphoid tissue lymphoma on a 1.5-T MR-Linac

We developed and evaluated a multiplane cine magnetic resonance imaging (MRI) workflow for magnetic resonance (MR)-guided online adaptive radiation therapy (MRgOART) for gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Two patients underwent MRgOART using this workflow, which enabled real-time assessments of stomach motion and ensured accurate target coverage within a planning target volume. Our workflow allowed visualization of the stomach with complex intrafractional motion caused by respiration and peristalsis. The total treatment time was clinically acceptable. All fractions satisfied our dose constraints. Our workflow supports precise MRgOART delivery for targets with variable shapes and motion, such as gastric MALT lymphoma.
