CyberKnife frameless image-guided radiosurgery has become a widely used system for parenchymal extracranial lesions. Gold fiducials are required for the planning and aiming of CyberKnife therapy. We report our initial experience and describe the technique of positioning tumor markers, under CT guidance. We conducted a retrospective review of 105 patients who were referred for CyberKnife stereotactic radiosurgery at Iatropolis CyberKnife Center in Athens. All patients underwent percutaneous fiducial placement via CT guidance. At the desired location, the 18-G needle was advanced into or near the tumor. Data collected included number and locations of fiducials placed and complications experienced to date. One hundred five patients underwent fiducial placement under CT guidance and a total number of 319 gold seeds were implanted. We experienced one episode of pneumothorax that required drainage, one mild pneumothorax, and three episodes of perifocal pulmonary hemorrhage. In conclusion, fiducial implantation under CT guidance appears to be a safe and efficient procedure, as long as it is performed by an experienced interventional radiologist.
无框架 CyberKnife 图像引导放射外科已成为治疗实质外颅病变的广泛应用系统。CyberKnife 治疗需要金基准标记进行规划和定位。我们报告了我们的初步经验，并描述了在 CT 引导下定位肿瘤标记物的技术。我们对在雅典 Iatropolis CyberKnife 中心接受 CyberKnife 立体定向放射外科治疗的 105 名患者进行了回顾性研究。所有患者均通过 CT 引导进行经皮基准标记放置。在所需的位置，18-G 针推进或靠近肿瘤。收集的数据包括放置的基准标记的数量和位置以及迄今为止遇到的并发症。105 名患者在 CT 引导下进行了基准标记放置，共植入了 319 个金种子。我们经历了一次气胸需要引流，一次轻度气胸和三次肺周出血。总之，只要由经验丰富的介入放射科医生进行，CT 引导下的基准标记植入似乎是一种安全有效的方法。
