Contrast Enhanced Ultrasound in Neurosurgery to Improve Glioma Visualization and Border Demarcation

This study plans to learn more about using contrast enhanced ultrasound (CEUS) in brain tumor surgery. The goal of glioma brain tumor surgery is to remove as much of the glioma as possible. Tumor tissue that is close to normal brain tissue can look very similar. This can make it difficult for the surgeon to remove all the tumor. In this study, we hope to learn if using CEUS during brain tumor surgery will allow the brain surgeon to better see and remove all the tumor tissue.
