摘要

目的 评估在肝脏放射栓塞治疗过程中使用新型核与透视混合 C 臂扫描仪的安全性和可行性。材料和方法 在这项前瞻性的首次人体临床研究中,共纳入了 12 名接受钇 90 放射栓塞检查的肝脏肿瘤患者(中位年龄 67 岁 [范围:37-78 岁];男性 9 人 [75%],女性 3 人 [25%])(ClinicalTrials.gov NCT06013774)。工作检查血管造影和锝99m宏观白蛋白注射是在血管造影室进行的,该造影室配备了可同时进行透视和平面核成像的混合C型臂。在实时混合成像下注射锝 99m 巨聚白蛋白,然后进行室内 SPECT 成像。通过评估不良事件、技术性能、额外的 X 射线辐射剂量以及放射科医生和技术人员填写的调查问卷,对安全性和可行性进行了研究。结果 混合 C 臂扫描仪未发生任何不良事件。额外的 X 射线辐射剂量较低(中位数:19 Gy - cm2;最小值:12 Gy - cm2;最大值:12 Gy - cm2):平方厘米;最低:12 Gy - cm2;最高:21 Gy - cm221 Gy - cm2)。介入人员认为使用混合 C 臂扫描仪安全可行,但介入室的额外时间较长(中位数:64 分钟;最少:55 分钟;最多:1 分钟):55分钟;最长完成所有成像步骤的参与者需要 77 分钟)。结论 在这项首次进行的人体临床研究中发现,在肝脏放射性栓塞术的检查过程中使用混合 C 臂扫描仪是安全可行的。关键词血管造影 透视 介入血管 放射性核素研究 放射外科 伽玛刀 赛博刀 SPECT 仪器 物理 技术方面 技术评估 本文有补充材料。以 CC BY 4.0 许可发布。临床试验注册号:NCT06013774。NCT06013774。

Safety and Feasibility of Interventional Hybrid Fluoroscopy and Nuclear Imaging in the Work-up Procedure of Hepatic Radioembolization.

Purpose To evaluate the safety and feasibility of a novel hybrid nuclear and fluoroscopy C-arm scanner to be used during the work-up procedure of hepatic radioembolization. Materials and Methods In this prospective first-in-human clinical study, 12 participants (median age, 67 years [range: 37-78 years]; nine [75%] male, three [25%] female) with liver tumors undergoing work-up for yttrium 90 radioembolization were included (ClinicalTrials.gov NCT06013774). Work-up angiography and technetium 99m-macroaggregated albumin injection were performed in an angiography suite equipped with a hybrid C-arm that could simultaneously perform fluoroscopy and planar nuclear imaging. Technetium 99m-macroaggregated albumin was injected under real-time hybrid imaging, followed by in-room SPECT imaging. Safety and feasibility were studied by assessing adverse events, technical performance, additional x-ray radiation dose, and questionnaires completed by radiologists and technologists. Results No adverse events were attributed to the hybrid C-arm scanner. The additional x-ray radiation dose was low (median, 19 Gy · cm2; minimum: 12 Gy · cm2; maximum: 21 Gy · cm2 for participants who completed all imaging steps). The interventional personnel considered use of the hybrid C-arm scanner safe and feasible, although the additional time spent in the intervention room was considered long (median, 64 minutes; minimum: 55 minutes; maximum: 77 minutes for participants who completed all imaging steps). Conclusion Use of the hybrid C-arm scanner during the work-up procedure of hepatic radioembolization was found to be safe and feasible in this first-in-human clinical study.
