This is a single arm, single center study of 15 patients with brain lesions being treated at UNC Hospitals. Subjects will undergo one (1) FLT-PET-MRI scan before their scheduled surgical biopsy of their brain lesion(s).

Official Title: FLT PET/MR for Evaluation of Pseudoprogression in Patients With Brain Lesions

Further study details as provided by UNC Lineberger Comprehensive Cancer Center:

Primary Outcome Measures:
  • Sensitivity and specificity of FLT-PET-MRI in distinguishing between recurrence and radiation necrosis, with surgical biopsy as gold standard [ Time Frame: 1 week post-surgical biopsy ]

Estimated Enrollment: 15
Study Start Date: June 2014
Estimated Study Completion Date: June 2018
Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions

All participants will have known brain lesion in the central nervous system (CNS) scheduled to have surgical biopsy of the lesion, identified by the UNC Brain Tumor Board and will have the clinical question of radiation necrosis vs. recurrence.

All participants will receive a FLT PET/MR scan.

Each participant will be injected with FLT, a common PET radiotracer for brain tumors and lesions, and then will complete one (1) PET/MR scan.
Other Name: FLT PET/MRI

Detailed Description:
Identifying imaging biomarkers of metastatic brain tumor treatment response could allow early modification of treatment by determination of tumor progression vs. treatment related effects (pseudo-progression, radiation necrosis). Earlier treatment response assessment could reduce cost, improve clinical trial efficiency and allow better assessment of prognosis. The development of PET/MRI offers the possibility of combining the functional imaging of PET with the exquisite soft tissue contrast and physiologic imaging capabilities of MRI. Combining FLT-PET imaging with MRI may allow better evaluation of new and unclear lesions in brain metastatic disease. The goal of this study is to explore FLT-PET imaging combined with dynamic MR imaging techniques for the identification of tumor response markers in metastatic brain tumors.

Inclusion Criteria:
