For MR-guided radiation therapy treatment planning, an MRI and CT of the intended treatment site are typically acquired. Patients' prior treatments or procedures can cause image artifacts in one or both scans, which may impact treatment planning or the radiation dose calculation. In this case report, a patient with several previous transcatheter arterial chemoembolization (TACE) procedures was planned for radiation therapy on a low-field MR-linac, and the impact of residual iodinated oil on the radiation dose calculation and MR-guided adaptive workflow was evaluated.
对于磁共振引导放射治疗的治疗计划，通常会获取预期治疗部位的磁共振成像（MRI）和计算机断层扫描（CT）。患者先前的治疗或操作可能会在一次或两次扫描中导致图像伪影，这可能会影响治疗计划或辐射剂量计算。在本病例报告中，一名曾接受过多次经动脉化疗栓塞术（TACE）的患者计划在低场磁共振直线加速器上进行放射治疗，并评估了残留碘化油对辐射剂量计算和磁共振引导的自适应工作流程的影响。
