[Flat-detector computed tomography in diagnostic and interventional neuroradiology]

Area of Science:

• Radiological imaging technology
• Medical physics
• Neuroradiology

Context:

• Flat-detector computed tomography (FD-CT) technology has evolved from standard radiography improvements.
• It is now a widely adopted tool for advanced neuroangiographic imaging procedures.
• FD-CT utilizes rotational C-arm mounted flat-panel detectors for high-resolution volumetric imaging.

Purpose:

• To review the technical principles of flat-detector (FD) technology.
• To explore the diverse applications of FD-CT in diagnostic and interventional neuroradiology.
• To highlight FD-CT's utility in neurovascular interventions and other radiological procedures.

Summary:

• FD-CT offers CT-like morphologic images within angiography suites, enabling rapid periprocedural complication assessment.
• Applications include intracranial stenting, aneurysm coiling, arteriovenous malformation embolization, myelography, and spinal interventions.
• Potential applications extend to temporal bone imaging, showcasing its versatility.

Impact:

• FD-CT improves diagnostic accuracy and procedural management in neuroradiology.
• It enhances patient safety by allowing rapid detection of complications like hemorrhaging.
• The technology streamlines workflows by enabling multimodal imaging within a single suite, reducing patient transfer needs.
