Combined Angio-CT Systems: A Roadmap Tool for Precision Therapy in Interventional Oncology

Area of Science:

• Interventional Radiology
• Medical Imaging
• Oncology

Background:

• Combined angiography-CT (angio-CT) systems integrate traditional angiography with cross-sectional imaging.
• Cone-beam CT (CBCT) is established but angio-CT offers superior soft-tissue imaging and contrast resolution.
• Renewed interest in angio-CT for interventional oncology due to improved workflow, affordability, and usability.

Purpose of the Study:

• To provide a comprehensive technical and clinical guide for angio-CT systems in interventional oncology.
• To discuss basic concepts including workflow, imaging characteristics, and acquisition parameters.
• To review clinical applications and benefits in therapeutic and palliative interventional oncology procedures.

Main Methods:

• Review of technical aspects of angio-CT systems.
• Discussion of imaging characteristics and acquisition parameters.
• Overview of clinical applications in interventional oncology.

Main Results:

• Angio-CT systems are a viable alternative to stand-alone systems with CBCT.
• Improved workflow enhances affordability and usability.
• Demonstrated benefits in therapeutic and palliative interventional oncology procedures.

Conclusions:

• Angio-CT systems are valuable tools for interventional radiology and oncology.
• These systems offer advantages in soft-tissue imaging and contrast resolution.
• Comprehensive understanding of technical and clinical aspects is crucial for optimal use.
