Comparison of PET/CT vs. PET/MRI Using 2 Radiopharmaceuticals

Comparison of PET/CT vs. PET/MRI

This clinical trial studies how well positron emission tomography (PET)/computed tomography (CT) works compared to PET/magnetic resonance imaging (MRI) in evaluating patients with cancer. PET/CT and PET/MRI may determine which scanner is best for the patient's type of cancer and other types of cancers.

PRIMARY OBJECTIVES:

I. To evaluate if PET/CT and PET/MRI scanners provide equivalent results for evaluation of cancer patients.

OUTLINE:

Patients receive standard of care 18F-fludeoxyglucose (FDG) or Ga68-DOTA-TATE intravenously (IV). Within 45-60 minutes, patients then undergo PET/CT imaging immediately followed by PET/MRI. Each participant is to receive 18-FDG or 68Ga-DOTA-TATE only, no participant was to receive both radiotracers.

INCLUSION CRITERIA

• Cancer diagnosis
• Capable of complying with study procedures
• Able to remain still for duration of imaging procedure (approximately 90 minutes total)
• Written informed consent

EXCLUSION CRITERIA

• Pregnant or nursing
• Metallic implants
• Impaired renal function
