Brain Infarct Segmentation and Registration on MRI or CT for Lesion-symptom Mapping

Published on: September 25, 2019

  • Bridge Burner achieved low segmentation errors: 3.4% volume mismatch and 0.34 mm surface mismatch.
  • Performance was comparable to expert disagreement (3.8% volume, 0.48 mm surface).
  • Bridge Burner outperformed BET (8.3% volume mismatch) and processed datasets in 7 seconds.

Conclusions:

  • Bridge Burner provides accurate and automated brain segmentation for high-resolution T1-weighted MRI.
  • The algorithm demonstrates potential as an efficient tool in neuroimaging research.
