Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Biomedical Engineering

Background:

  • Standard MR head coils present limitations for interventional procedures.
  • Brain biopsies require precise guidance and sterile conditions.

Purpose of the Study:

  • To describe the technical realization and application of inductively coupled surface coils for interventional MR-guided brain biopsies.
  • To evaluate the advantages of these coils over standard coils.

Main Methods:

  • Development of inductively coupled surface coils for a 0.2 T magnet.
  • Application of coils in 26 brain biopsies across eight neuropathologic diagnoses.
  • Comparison with standard MR head coils.

Main Results:

  • Inductively coupled coils facilitate interventional procedures in the brain.
  • Improved handling of sterility was observed.
  • Enhanced surgical access was frequently noted.

Conclusions:

  • Inductively coupled surface coils increase indications for interventional brain procedures.
  • These coils provide practical benefits in terms of sterility and surgeon access.
  • Initial experience suggests a valuable role in MR-guided neurointerventions.
