Assessment of Eloquent Function in Brain Tumor Patients

Study Purpose

Purpose of the study: AIM 1 Prospectively collect pre-operative (fMRI, DTI, 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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 19 Years and Over
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Patients 19 years and older. 2. Brain tumor in or near eloquent brain regions that is appropriate for attempted resection. 3. Appropriate body habitus and mental status/capacity to participate with non-invasive or invasive mapping. 4. Benign or malignant intra-axial brain tumor. 5. Primary or metastatic intra-axial brain tumor.

Exclusion Criteria:

1. Any patient with a contraindication to MRI (i.e. implanted devices) 2. Inappropriate body habitus or mental status/capacity to participate with non-invasive or invasive mapping in a safe and reliable manner. 3. Patient declines to participate. 4. Patient that does not have the capacity to understand the study or consent for themselves. 5. Neurologic status which precludes them from testing (poor function- not testable). 6. Positive pregnancy test in females. 7. Any patient with end stage renal disease or severe renal dysfunction.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Any patient with a primary or metastatic brain tumor in or near an eloquent area would be eligible for participation in the study assuming no contraindications to any of the studies or operative procedure. Pre-operative: Evaluation will include clinical evaluation, neuropsychological testing, MRI brain with and without contrast, fMRI, DTI tractograms, and MEG studies as well as standard pre-operative work-up. Intra-operative: All non-invasive pre-operative mapping data will be incorporated into the operative procedure with the imaging tools that we routinely use during neurosurgical procedures. Patients will have awake mapping performed. Our usual standards of care will be followed during craniotomy, mapping, and tumor resection or biopsy. Post-operative: Patients will have routine post-operative care and assessment consisting of clinical examinations and imaging obtained within 24 hours post resection. They will have routine follow-up outpatient appointments after surgery which will include neurologic assessment and follow-up imaging (MRI with and without contrast) for their tumors as appropriate. The experimental portion of the protocol is incorporating repeat neuropsychological testing and mapping studies (fMRI, DTI, MEG) studies at 2 and 6 months post-surgery into their routine follow-up.
