图像融合可用于以前的成像（例如正电子发射断层扫描、磁共振成像或对比增强计算机断层扫描 (CT)）定义参考程序成像、针或导管或超声换能器的信息的任何手术。术前和术中成像的融合提供了有关肿瘤位置或边缘、代谢活动、设备位置或血管位置的实时反馈。介入放射学中的多模态图像融合最初被引入用于活检和消融，特别是对于仅在动脉期 CT、磁共振成像或正电子发射断层扫描/CT 上看到的病变，但最近已应用于其他血管和非血管手术。图像融合和导航通常使用两种不同类型的平台：(1) 电磁跟踪和 (2) 锥束 CT。将对这两种技术及其优点和缺点、适应症、何时使用一种技术、何时使用一种技术、简化使用的提示和指南以及定义这些快速发展、商业化和新兴技术的临床益处的早期证据进行审查。
Image fusion may be useful in any procedure where previous imaging such as positron emission tomography, magnetic resonance imaging, or contrast-enhanced computed tomography (CT) defines information that is referenced to the procedural imaging, to the needle or catheter, or to an ultrasound transducer. Fusion of prior and intraoperative imaging provides real-time feedback on tumor location or margin, metabolic activity, device location, or vessel location. Multimodality image fusion in interventional radiology was initially introduced for biopsies and ablations, especially for lesions only seen on arterial phase CT, magnetic resonance imaging, or positron emission tomography/CT but has more recently been applied to other vascular and nonvascular procedures. Two different types of platforms are commonly used for image fusion and navigation: (1) electromagnetic tracking and (2) cone-beam CT. Both technologies would be reviewed as well as their strengths and weaknesses, indications, when to use one vs the other, tips and guidance to streamline use, and early evidence defining clinical benefits of these rapidly evolving, commercially available and emerging techniques.
