The radioactive nature of the solution allows the scanner to "see" it in certain places in your body. You will receive the solution by vein through a catheter. A central venous catheter is a sterile flexible tube that will be placed into a large vein while you are under local anesthesia. Your doctor will explain this procedure to you in more detail, and you will be required to sign a separate consent form.\n\nAfter the injection, you will need to rest quietly until it is time for the scan. The amount of rest time may vary, but be prepared to wait for about 60 minutes. During the scan, you will lie flat on your back on a table. After the solution is injected into a vein, the PET scanner takes pictures of the radioactive solution as it moves through the body and collects at various sites in the body. By watching how the solution travels through the body and studying where the solution collects, researchers may be able to learn where the disease is in your body. The entire procedure should last about 60-70 minutes.\n\nYou must not eat or drink anything except water for at least 6 hours before the FLT PET scan.\n\nAbout 2 minutes after the FLT solution is injected, blood (about 10 teaspoons) will be drawn from the catheter. This blood will be drawn to measure how much FLT is in your body and may help the study staff understand the images better.\n\nLength of Study:\n\nAfter the FLT PET scan is complete, your active participation on this study will be over.\n\nFollow-Up Medical Record Review:\n\nAbout 30 days after the FLT PET scan, you will be contacted by phone by the study staff to check if you are having any side effects. The phone call should last about 15 minutes.\n\nYour medical records will continue to be reviewed for up to an additional 5 years to learn how you are doing, what other treatments you may have had and how they worked, if you had any new brain problems, or if the tumor came back.\n\nThis is an investigational study. The 3\'-Deoxy-3\'-18f-Fluorothymidine solution is not FDA approved or commercially available. At this time, 3\'-Deoxy-3\'-18f-Fluorothymidine solution is only being used in research.\n\nUp to 20 patients will take part in this study. All will be enrolled at MD Anderson.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1. Patient is \\>/= 18 years old, agrees to participate in the clinical study and to complete all required visits and evaluations. The pediatric population has a different disease profile from the glioma patients we hope to recruit. To reduce heterogeneity in the patient population we will not consider patients younger than 18 for this study.\n2. Patient is a candidate for cerebral tumor resection due to an enhancing brain lesion, with history of previous pathologically proven primary brain tumor (WHO grade II-IV diffuse glioma)\n3. Patient had diffuse glioma (WHO grade 2 - 4) and as part of their treatment received radiation therapy and Temozolomide (a first-line chemotherapeutic agent).\n4. Patient will have subsequently developed an enhancing brain mass greater than 1cm in diameter, at least 6 months after finishing radiation therapy (to differentiate from the more acute treatment related effect of "pseudo-progression").\n5. As the predominate means of determining TRN versus recurrent glial tumor at MD Anderson, a brain tumor/ necrosis protocol is ordered as clinically indicated.\n6. Patient\'s clinician based on the clinical and MR information wants to proceed with biopsy or surgical resection within 30 days from when the brain tumor MR protocol was performed. The patient meets with the neurosurgeon and agrees to surgical biopsy or resection.\n7. Patient is able to understand and give consent to participation in the study\n8. Patient has received as part of their care the Brain Tumor Imaging protocol.\n9. Patient agrees to undergo, prior to the procedure, FLT PET at CABI\n\nExclusion Criteria:\n\n1. The patient is found to have unfavorable anatomy to indicate that stereotactic biopsy/ resection could not be safely performed\n2. Claustrophobia that does not readily respond to oral medication\n3. Allergy to Fluoro-L-Thymidine\n4. Pregnant or lactating (Based on self-reported and clinical care testing with physicians before study participation)'}, 'identificationModule': {'nctId': 'NCT02241668', 'briefTitle': 'Fluoro-L-Thymidine Positron Emission Tomography (FLT PET) vs. Adv.
