Implication

Prospective observational study evaluates combined imaging strategies for better tumor resection in glioma, suggesting improved outcomes.

Key Points

This research aims to evaluate the effectiveness of combining intraoperative ultrasonography (IOUS) and intraoperative MRI (IOMRI) for glioma resections.
Conducted a prospective observational study over two years
Included patients with gliomas in eloquent regions
Utilized IOUS for guiding pre-resection and monitoring during surgery
Implemented IOMRI at the end of the resection to confirm outcomes
Included 34 patients with a median extent of resection (EOR) of 91.42%
Observed a median residual tumor volume of 4.46 cc
29.4% of patients underwent further resection after IOMRI, increasing median EOR by 10%
Sensitivity of IOUS for residual tumor detection was 85% with 100% specificity compared to IOMRI
Concordance of EOR estimates between IOUS and IOMRI was 64.7%
