A new Bone Fusion function enhances 3D-Angio in neuroradiology. It clearly visualizes skull base and aneurysm relationships, improving treatment strategy for complex cases.

Area of Science:

  • Neuroradiology
  • Medical Imaging
  • Interventional Radiology

Background:

  • Three-dimensional angiography (3D-Angio) is crucial for cerebral aneurysm evaluation.
  • Current 3D-Angio modes (3D-DSA, 3D-DA) can struggle to delineate adjacent vascular and osseous structures.
  • Accurate assessment of skull base and aneurysm proximity is vital for treatment planning.

Purpose of the Study:

  • To introduce and evaluate the Bone Fusion function for improved visualization of vascular and osseous structures.
  • To enhance the determination of relationships between skull base and intracranial pathologies.

Main Methods:

  • Developed the Bone Fusion function to reconstruct and fuse separate 3D datasets of vessel and bone structures.
  • Utilized rotational DSA and mask sequence data.

  • Employed three display modes: fusion, vessel only, and bone only, with color differentiation.

    • Main Results:

    • Bone Fusion successfully reconstructed and fused vessel and bone data in hundreds of clinical cases.
    • The function provided critical information for treatment strategy, especially when structures were closely approximated.
    • It proved particularly useful for aneurysms and tumors adjacent to the skull base.

    Conclusions:

    • The Bone Fusion function significantly improves the assessment of vascular and osseous relationships in neuroradiology.
    • This technique offers crucial insights for treatment planning in complex cases involving skull base pathologies.
