PET (positron emission tomography) scans combined with a radioactive tracer will be used to identify and analyze tumors. Currently, the most common tracer used to analyze neuroblastoma tumors is called 123I-mIBG. However, the picture it provides is not always clear enough to see the very small areas of the disease. 18F-DA (18F-fluorodopamine) has been shown to be safe and more effective than 123I-mIBG in analyzing the tumor pheochromocytoma, which is closely related to neuroblastoma. With this research study, the investigators plan to meet the following goals:
Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||1 Year and Over|
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Neuroblastoma is the most common extracranial malignant tumor of childhood. Nuclear imaging with 123I-mIBG is the standard test to follow and manage these patients. Because of the inherent imaging characteristics of I-123, there is suboptimal resolution within the images, causing them to appear somewhat blurry, which reduces our ability to find small areas of disease. A chemical that uses positron emission tomography should allow much better resolution of the images, which could improve patient care by allowing us to find small areas of disease that, if untreated, could result in tumor relapse. We have developed 18F-fluorodopamine (18F-DA) for PET imaging in our patients with neuroblastoma. The primary objective is to explore the safety of 18F-DA in patients with known or suspected neuroblastoma or pheochromocytoma. The secondary objectives are to evaluate the biodistribution of 18F-DA in patients with neuroblastoma and compare the biodistribution of 18F-DA with the biodistribution of 123I-mIBG. Patients receive an intravenous injection of a small (tracer) dose of 18F-DA. Approximately 1 hour later, patients undergo PET scanning of the entire body to evaluate the localization of the tracer.
Experimental: Injection of 18F-DA
18F-DA will be injected into a vein in the arm or leg, or via central venous access line.
Drug: - 18F-DA
18F-DA is an investigational PET radiotracer
