[Clinical application of flat-panel CT in the angio suite]

Area of Science:

• Medical Imaging
• Interventional Radiology
• Radiological Technology

Background:

• Modern angiographic C-arm systems equipped with flat-panel detectors facilitate CT-like imaging acquisition within the angiography suite, termed flat-panel CT (FD-CT).
• FD-CT represents a novel imaging modality with distinct technical characteristics, advantages, and limitations.

Purpose of the Study:

• To provide a technical overview of FD-CT, including its pros and cons.
• To describe the most common and well-evaluated clinical indications for FD-CT.
• To highlight the potential and limitations of FD-CT in various interventional procedures.

Main Methods:

• Review of technical aspects and clinical applications of flat-panel CT.
• Discussion of established and emerging indications based on current literature and practice.
• Comparative analysis of FD-CT radiation exposure relative to conventional CT.

Main Results:

• FD-CT is a valuable adjunctive tool in neurointerventional procedures and embolizations, particularly liver embolization.
• Musculoskeletal interventions and complex peripheral vascular interventions, including stent-graft procedures, are attractive indications for FD-CT.
• The utility of FD-CT is influenced by operator experience and innovation, but it entails additional radiation exposure comparable to spiral CT.

Conclusions:

• FD-CT offers a broad spectrum of applications in interventional radiology, enhancing diagnostic capabilities during procedures.
• Key indications include neurointerventions, liver embolization, musculoskeletal interventions, and complex vascular procedures.
• Awareness of FD-CT's radiation dose, similar to spiral CT, is crucial for its appropriate utilization.
