Brief Summary
This pilot clinical trial studies fluorine F 18 fluorodopa (18F-DOPA)-positron emission tomography (PET) in planning surgery in patients with gliomas. New imaging procedures, such as 18F-DOPA-PET scan, may help find gliomas and may help in planning surgery.

Outcome Measures
Primary Outcomes (1)
Ratios of maximum tumor standardized uptake value (SUVmax) normalized to mean SUV (SUVmean) of T/N
To determine the optimal PET threshold for distinguishing HGG from LGG brain tissue, receiver operating characteristic (ROC) analysis and the Youden's index (sum of the sensitivity and specificity - 1) will be used. The Youden's index will be calculated for each possible T/N threshold. The final ROC area under the curve (AUC) value and confidence intervals will be estimated using ROC analysis methods for clustered continuous data as described by Obychowski.
Up to 1 year
Secondary Outcomes (5)
Differences in volumes generated from biopsy-validated thresholds evaluated by 18F-DOPA-PET, pMRI, and DTI
Up to 5 years
Histologic grade of the specimen defined as HGG, LGG, or non-malignant brain tissue
Up to 5 years
MRI contrast enhancement values
Up to 5 years
Progression free survival
The time from study entry to progression, assessed up to 5 years
Proportion of patients whose maximum 18F-DOPA uptake samples are in agreement with the final diagnostic grade
Up to 5 years
Other Outcomes (3)
Accurate identification of the highest grade/highest density disease
Up to 5 years
Accurate identification of tumor extent
Up to 5 years
Role of metabolic imaging in neurosurgical resection planning
Up to 5 years
Study Arms (1)
Diagnostic (18F-DOPA-PET)
EXPERIMENTALWithin 1 week of biopsy or resection, patients undergo 18F-DOPA PET/CT scan and pMRI and DTI at baseline. Patients then undergo stereotactic craniotomy or image-guided biopsy.
Interventions
