Summary
Brain surface motion imaging helps predict tumor-brain adhesion in meningioma surgery. The single acquisition method showed higher accuracy (76.5%) than the double acquisition method (69.7%) in predicting adhesion.
Area of Science:
- Neurosurgery
- Radiology
- Medical Imaging
Background:
- Adhesions between the brain and meningioma impact surgical removal success.
- Brain surface motion imaging assesses brain surface dynamics.
- Lack of a stripe pattern on tumor surface indicates adhesion.
Purpose of the Study:
- Evaluate accuracy of predicting tumor-brain adhesion.
- Compare double acquisition vs. single acquisition methods for brain surface motion imaging.
Main Methods:
- 67 meningioma patients undergoing surgery were analyzed.
- Brain surface motion imaging was performed pre-surgically.
- 33 cases used double acquisition, 34 used single acquisition.
Main Results:
- Double acquisition method agreed with surgical findings in 69.7% of cases.
- Single acquisition method agreed with surgical findings in 76.5% of cases.
Conclusions:
- Brain surface motion imaging aids pre-surgical evaluation for meningioma.
- The single acquisition method is more accurate for predicting tumor-brain adhesion.
