Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The diagnosis for the participants will be either low grade gliomas. A baseline fMRI and follow up routine fMRI's will be taken and evaluated for any changes in perfusion. During the scans, The ultrasound placement will last for one hour.
This study seeks to investigate the efficacy of focused ultrasound in opening the blood brain barrier. This physiological effect would have significant clinical applications. The ability to open the blood brain barrier has the potential to revolutionize the delivery of therapeutic agents to the brain, allowing for more localized and efficient delivery. There are no immediate benefits for patients who choose to participate; however, the information gained from this study will contribute to the research base and help patients in similar situations in the future.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Focused Ultrasound
The ultrasound treatment will last either 1 hour or 20 minutes total time for the DWL device or Brainsonix Focused Ultrasound Device, respectively.
Focused Ultrasound
With focused ultrasound, there is an expected accentuation of local perfusion and potential temporary opening of the blood brain barrier with the aim is to provide better delivery of therapeutic agents including medication, particulates and cellular elements for treatment of neoplastic, inflammatory and degenerative brain diseases. The present study seeks to investigate differences in perfusion between areas treated and untreated by this modality in order to further explore its use in clinical application for the treatment of brain disease.
