本研究旨在探讨超声-CT融合导航技术在骨肿瘤活检手术中的临床应用价值。将30例需要活检手术的骨肿瘤患者随机分为U-C组（超声-CT组，n=15） ）或对照组（n=15）。 U-C组利用超声-CT融合导航技术对活检针进行实时定位，对照组则依靠术中C形臂透视进行定位。比较两组手术成功率、术中受辐射次数、手术时间、术中出血量。U-C组术中受辐射次数为2次，对照组为7次（P< 0.05），显示两组之间存在显着差异。 U-C组与对照组活检成功率均为100%（P＞0.05），平均手术时间分别为45±9min vs 42±13min（P＞0.05），术中出血量分别为10±4ml vs 11±4ml。 5ml（P＞0.05），两组间均无显着性差异。骨肿瘤活检手术中利用超声-CT融合导航技术对活检针进行实时定位，可显着减少术中患者和术者的辐射暴露。步骤。因此，该技术具有一定的临床适用性。版权所有 © 2023 Elsevier Inc. 保留所有权利。

This study aims to investigate the clinical application value of ultrasound-CT fusion navigation technology in bone tumor biopsy surgery.A total of thirty patients with bone tumors requiring biopsy surgery were randomly assigned to either the U-C group (ultrasound-CT group, n=15) or the control group (n=15). The U-C group utilized ultrasound-CT fusion navigation technology for real-time localization of the biopsy needle, while the control group relied on intraoperative C-arm fluoroscopy for localization. The success rate of the surgeries, the number of radiation exposures during the procedure, surgical time, and intraoperative blood loss were compared between the two groups.Number of intraoperative radiation exposure in the U-C group was 2 versus 7 in the control group (P<0.05), showing significant differences between the 2 groups. The success rate of biopsies in the U-C group and control group was 100%(P＞0.05), the mean operative time was 45±9min versus 42±13min (P＞0.05), and intraoperative bleeding volume was 10±4ml versus 11±5ml(P＞0.05), all showing no significant differences between the 2 groups.The real-time localization of the biopsy needle in bone tumor biopsy surgery using ultrasound-CT fusion navigation technology can significantly reduce intraoperative radiation exposure for both patients and surgeons during the procedure. Consequently, this technique holds certain clinical applicability.Copyright © 2023 Elsevier Inc. All rights reserved.
