Summary
Near real-time neuro-navigation using open MRI enhances precision for stereotactic abscess evacuation. This advanced imaging reveals anatomical changes and inflammatory processes during surgery.
Area of Science:
- Neurosurgery
- Medical Imaging
Background:
- Stereotactic evacuation of intracranial abscesses requires precise guidance.
- Open MRI systems offer potential for real-time intraoperative imaging.
Observation:
- A 70-year-old patient with a left temporal abscess underwent stereotactic evacuation guided by open MRI.
- Near real-time imaging visualized an 11 mm indentation along the trajectory.
- Thermosensitive MRI detected temperature gradients around the abscess, indicating inflammation.
Findings:
- The procedure successfully evacuated the abscess, with a recurrence also managed.
- Near real-time MRI demonstrated dynamic anatomical changes during the intervention.
- Thermosensitive MRI effectively highlighted the inflammatory nature of the abscess capsule.
Implications:
- Open MRI-guided neuro-navigation improves precision in stereotactic procedures.
- Real-time imaging capabilities enhance surgical accuracy and safety.
- Thermosensitive MRI protocols can aid in characterizing inflammatory processes during interventions.
