Assessment of Eloquent Function in Brain Tumor Patients
What this study is about
Purpose of the study: AIM 1: Prospectively collect pre-operative \[functional magnetic resonance imaging (fMRI), diffusion tensor imaging (DTI), magnetoencephalography (MEG)\] and intra-operative mapping data in patients with intra-axial brain tumors to assess how well each modality predicts the location of eloquent brain function. In addition, each modality will be compared with the other.

Purpose of the study: AIM 1: Prospectively collect pre-operative \[functional magnetic resonance imaging (fMRI), diffusion tensor imaging (DTI), magnetoencephalography (MEG)\] and intra-operative mapping data in patients with intra-axial brain tumors to assess how well each modality predicts the location of eloquent brain function. In addition, each modality will be compared with the other. AIM 2: Assess reorganization of eloquent brain function and plasticity in patients with intra-axial brain tumors. This will be accomplished by prospectively collecting post-operative mapping studies and neuropsychological tests to compare them to prior mapping studies as stated above.
Interventions
DIAGNOSTIC_TEST
Brain mapping
Brain mapping will be employed pre-, intra-, and post-operatively to evaluate specific functions.
Primary outcome measures
Eloquent function
Time frame: 1 year
The location of the eloquent function of interest (motor, sensory, speech) will be assessed pre-operatively and intra-operatively and compared. Then, at 2 and 6 months post-operatively, repeat non-invasive mapping studies will be performed to compare to the subjects' prior studies. This will allow for assessment of reorganization and plasticity of function. Additionally, novel ways of identifying eloquent brain regions will be developed.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- 19 years and older
- Brain tumor in or near eloquent brain regions that is appropriate for attempted resection
- Appropriate body habitus and mental status/capacity to participate with non-invasive or invasive mapping
- Benign or malignant intra-axial brain tumor
- Primary or metastatic intra-axial brain tumor
Exclusion criteria
- Any contraindication to MRI (i.e. implanted devices)
- Inappropriate body habitus or mental status/capacity to participate with non-invasive or invasive mapping in a safe and reliable manner
- Declining to participate
- Lacks capacity to understand the study or consent for themselves
- Neurologic status which precludes testing (poor function- not testable)
- Positive pregnancy test
- End stage renal disease or severe renal dysfunction

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
