摘要:

文题释义:
多模态图像融合:是通过一定的算法,用多幅源图像(即输入图像)生成一幅或几幅图像的过程,生成的融合图像有着单一源图像所不具备的优点,含有更多、更准确的信息,从而更适合于人眼/机器视觉或者更适合后续的图像处理任务。
人工智能:是研究、开发用于模拟、延伸和扩展人的智能的理论、方法、技术及应用系统的一门新的技术科学。

背景:多模态医学图像融合技术目前多用于临床诊断、放射性治疗及病理变化的跟踪与治疗等,但联合智能机械臂辅助椎体强化临床应用较少。
目的:评价多模态图像融合联合智能机械臂辅助建立椎体强化通道的安全性和有效性。
方法:试验纳入骨质疏松性椎体压缩骨折椎体强化患者62例,随机分为2组,试验组31例采用多模态图像融合联合智能机械臂辅助建立椎体强化通道,对照组31例采用常规方法建立椎体强化通道。在相同规则下进行同一种骨水泥注入完成椎体强化。分别记录两组的术中指标、术后疼痛情况分及伤椎再骨折例数并进行统计学分析评定结果。
结果与结论:①与对照组相比,试验组的穿刺时间、透视次数、放射暴露总剂量、穿刺调整次数、骨水泥渗漏、定位时间和术后1 d疼痛目测类比评分均显著降低(P < 0.001),穿刺精度优良率、骨水泥注入量和骨水泥弥散优良率均显著升高(P < 0.001),两组定位透视次数无显著差异。②两组患者术后随访均未见感染,对照组1例患者在双肺动脉发现水泥栓子,1例患者术后疼痛长期无缓解,3例患者在术后6个月内因疼痛再发行MRI检查诊断伤椎再次骨折,而试验组随访时未见上述并发症。③结果证实,多模态图像融合联合智能机械臂辅助建立椎体强化通道可提高椎弓根定位穿刺的精准度及椎体强化效果,同时有效减少了术中放射暴露剂量及并发症的发生,安全可靠。

Abstract: BACKGROUND: Multi-modal medical image fusion technology is currently mostly used for clinical diagnosis, pathological change tracking and treatment, and radiotherapy, but the combined intelligent robotic arm assisted vertebral body augmentation is rarely used in clinical application.  
OBJECTIVE: To evaluate the safety and effectiveness of multi-modal image fusion combined with intelligent robotic arm assisted in establishing vertebral augmentation channels.
METHODS:  Sixty-two patients with osteoporotic vertebral compression fracture vertebral augmentation were included in this study and randomly divided into two groups. The 31 cases in the trial group underwent multi-modal image fusion by mechanical arm to build the vertebral strengthening channel. The 31 cases in the control group underwent conventional method to establish the vertebral strengthening channel. Vertebral augmentation was performed with the same bone cement injection under the same rules. The number of intraoperative index, postoperative pain score, and number of re-fractures of injured vertebrae were recorded. Statistical analysis was conducted to evaluate the results.  
RESULTS AND CONCLUSION: (1) The puncture time, fluoroscopy times, total dose of radiation exposure, puncture adjustment times, bone cement leakage, positioning time, and visual analogue scale score of pain 1 day after operation in the trial group were significantly lower than those in the control group (P < 0.001). The excellent and good rates of puncture accuracy, bone cement injection volume, and bone cement dispersion were significantly higher in the trial group than those in the control group (P < 0.001). The number of positioning fluoroscopy was not significantly different between the two groups. (2) No infection occurred in patients of the two groups. In the control group, one patient was found with cement emboli in the double pulmonary arteries; one patient had no long-term relief of postoperative pain; and three patients were diagnosed with re-fracture of injured vertebra due to pain reissue MRI examination within 6 months. No such complications were seen in the trial group during follow-up. (3) It is concluded that the establishment of vertebral enhancement channel assisted by multi-modal image fusion and intelligent robotic arm can improve the accuracy of pedicle localization and puncture and the effect of vertebral augmentation, and effectively reduce the number of fluoroscopy, radiation exposure dose and the occurrence of complications; it is safe and reliable.
