  • A Multicenter Trial of FDG-PET/CT Staging of Head and Neck Cancer and Its Impact on the N0 Neck Surgical Treatment in Head and Neck Cancer Patients (ACRIN 6685) Rochester, Minn.

    RATIONALE: Diagnostic procedures, such as fludeoxyglucose F 18-PET/CT scan, may help doctors find head and neck cancer and find out how far the disease has spread. It may also help doctors plan the best treatment.

    PURPOSE: This phase II trial is studying fludeoxyglucose F 18-PET/CT imaging to see how well it works in assessing the tumor and planning neck surgery in patients with newly diagnosed head and neck cancer.

  • Bridging Study of C11 PiB and F18 Flutemetamol Brain PET Rochester, Minn.

    The intent of this research protocol is to test the equivalency of two amyloid imaging drugs (C11 Pittsburgh Compound B and F18 Flutemetamol). The investigators hypothesize that there will be no significant difference in the distribution of the agents to areas of amyloid deposition in the brain or to other normal brain structures. Recent data have shown similarity in the distribution of the drugs in subjects with AD or mild cognitive impairment (MCI). No comparison data of the two PET drugs in normal subjects has been published. It is important to understand differences in the images and biodistribution from the two drugs in normal subjects as nonspecific accumulation of the drugs in brain structures such as white matter appear to differ slightly and could affect image performance.

    The current clinical functional imaging standard for patients with indeterminate cognitive impairment is FDG PET. To allow a comparison of the PET amyloid imaging compounds with FDG PET, FDG PET scans will also be important to acquire in the subjects for comparison.

  • Effect of Aging and Aerobic Exercise Training on Brain Glucose Metabolism Rochester, Minn.

    Aging is associated with a loss of brain function and conditions such as dementia and Alzheimer's disease. It is likely that decreased brain metabolism is contributing to the progression of age related degenerative diseases. Aerobic exercise training can increase brain volumes and is associated with decreased risk for degenerative brain conditions. However, little is know about the changes that occur to brain metabolism with aerobic training and aging.

  • Neuroimaging in African Americans Jacksonville, Fla., Rochester, Minn.

    The purpose of this study is to gather information and learn more about imaging tests in racially different people who are cognitively normal or have dementia.

  • Phase III Study of [18F]PSMA-1007 Positron Emission Tomography for the Detection of Prostate Cancer Lesions in Patients With Biochemical Recurrence After Previous Definitive Treatment for Localized Prostate Cancer (ABX-CT_303US) Rochester, Minn. This study evaluates the diagnostic performance and safety of [18F]PSMA-1007 PET/CT imaging in patients with suspected recurrence of prostate cancer after previous definitive treatment.
  • PSMA and C-11 Choline PET in Patients with Biochemical Recurrence of Prostate Cancer Rochester, Minn.

    The purpose of this study is to examine PSMA and C-11 Choline PET in patients with suspected metastatic prostate cancer who have been imaged with 11C-Choline PET clinically and with PSMA PET (either Gallium-68 labeled HBED-CC PSMA (more commonly called 68Ga-PSMA-11) or F-18 PSMA 1007) in order to demonstrate their utility in detecting prostate cancer.


  • Targeting Neuroinflammation as a Contributing Pathology in Alzheimer’s Disease Dementia Rochester, Minn.

    The purposes of this study are to determine if neuroinflammation, as measured by PET imaging, is associated with Ab plaques in cognitively impaired vs. cognitively unimpaired participants, to determine if neuroinflammation, as measured by neuroinflammation PET imaging, is associated with the rate of cognitive in the 5 years preceding PET imaging, and to determine if neuroinflammation, as measured by PET imaging, is associated with plasma biomarkers of inflammation.
