Image fusion during vascular and nonvascular image-guided procedures

Area of Science:

• Interventional Radiology
• Medical Imaging
• Image Fusion Technology

Background:

• Multimodality image fusion integrates pre-procedural imaging (PET, MRI, CT) with intraoperative data.
• This provides real-time feedback on critical elements like tumor margins, metabolic activity, and device placement.
• Initially used for biopsies and ablations, its application has expanded to diverse vascular and nonvascular procedures.

Purpose of the Study:

• To review the applications and benefits of multimodality image fusion in interventional radiology.
• To compare electromagnetic tracking and cone-beam CT platforms for image fusion and navigation.
• To provide guidance on selecting and utilizing these technologies effectively.

Main Methods:

• Review of existing literature and commercial platforms for image fusion.
• Comparison of electromagnetic tracking and cone-beam CT technologies.
• Analysis of clinical benefits and indications for image fusion techniques.

Main Results:

• Image fusion enhances visualization of targets and devices during interventional procedures.
• Electromagnetic tracking and cone-beam CT are two primary platforms with distinct strengths and weaknesses.
• Early evidence suggests clinical benefits for these evolving image fusion techniques.

Conclusions:

• Image fusion is a valuable tool in interventional radiology, improving procedural accuracy and safety.
• The choice between electromagnetic tracking and cone-beam CT depends on specific procedural requirements.
• Continued development of image fusion technologies promises further advancements in minimally invasive treatments.
