Spinal metastatic tumors are common and often cause debilitating symptoms. Image-guided percutaneous thermal ablation (IPTA) has gained significant recognition in managing spinal column tumors due to its exceptional precision and effectiveness. Conventional guidance modalities, including computed tomography, fluoroscopy, and ultrasound, have been important in targeting spinal column tumors while minimizing harm to adjacent critical structures. This study presents a novel approach utilizing a fusion of cone beam computed tomography with magnetic resonance imaging to guide percutaneous thermal ablation for four patients with secondary spinal column tumors. The visual analog scale (VAS) evaluated the procedure effectiveness during an 18-month follow-up. Percutaneous vertebroplasty was performed in two cases, and a thermostat was used during all procedures. Imaging was performed using the Stealth Station navigation system Spine 8 (SSS8) and a 1.5T MRI machine. The fusion of CBCT with MRI allowed for precise tumor localization and guidance for thermal ablation. Initial results indicate successful tumor ablation and symptom reduction, emphasizing the potential of CBCT–MRI fusion in spinal column tumor management. This innovative approach is promising in optimizing therapy for secondary spinal column tumors. Further studies are necessary to validate its efficacy and applicability.
脊柱转移性肿瘤较为常见,常导致患者出现衰弱性症状。影像引导下经皮热消融技术因其卓越的精确性和有效性,在脊柱肿瘤治疗中获得广泛认可。传统引导方式包括计算机断层扫描、透视和超声,在精准定位脊柱肿瘤同时最大限度减少对邻近关键结构的损伤方面发挥重要作用。本研究提出一种创新方法,采用锥形束计算机断层扫描与磁共振成像融合技术,为四例继发性脊柱肿瘤患者实施经皮热消融治疗。通过视觉模拟评分法在18个月随访期间评估手术效果。其中两例患者同期行经皮椎体成形术,所有手术过程均使用温度监测装置。影像导航采用Stealth Station Spine 8导航系统及1.5T磁共振设备。CBCT与MRI融合技术实现了肿瘤精确定位和消融过程精准引导。初步结果显示肿瘤消融成功且症状显著缓解,凸显了CBCT-MRI融合技术在脊柱肿瘤治疗中的应用潜力。该创新方法为优化继发性脊柱肿瘤治疗提供了新方向,其有效性与适用性仍需进一步研究验证。
