Hybrid procedure suites: combining computed tomography and conventional angiography

Area of Science:

• Medical Imaging
• Interventional Radiology
• Radiological Technology

Background:

• Interventional radiology relies on precise imaging for various procedural steps.
• Individual imaging modalities like computed tomography (CT), X-ray fluoroscopy, and ultrasound (US) have limitations.
• Optimal imaging requirements differ significantly between procedural phases.

Purpose of the Study:

• To evaluate the effectiveness of a combined computed tomography and angiography system in interventional radiology.
• To assess the imaging information needs at each stage of interventional procedures.
• To determine the suitability of integrated imaging systems compared to standalone modalities.

Main Methods:

• Evaluation of imaging requirements for planning, target access, device manipulation, and outcome confirmation in interventional radiology.
• Comparison of computed tomography (CT), X-ray fluoroscopy, and ultrasound (US) capabilities for each procedural step.
• Assessment of a combined angiography-computed tomography system integrating both modalities on a single platform.

Main Results:

• Computed tomography excels in 3D visualization for planning, while X-ray fluoroscopy is preferred for real-time device manipulation.
• No single modality perfectly fulfills all imaging needs, particularly for real-time target access.
• The integrated angiography-CT system offers a versatile solution, combining strengths for comprehensive procedural support.

Conclusions:

• A combined angiography-computed tomography system is highly beneficial for interventional radiology procedures.
• This integrated approach overcomes the limitations of individual imaging modalities across different procedural phases.
• The system facilitates accurate treatment delivery and improves overall procedural efficiency in interventional radiology.
