Validating Low FDG Dose PET/CT Compared to Current Standard of Care Dose PET/CT
- Conditions
- PET/CT Imaging
- Registration Number
- NCT03519659
- Lead Sponsor
- University of Cincinnati
- Brief Summary
The purpose of this study is to assess new low radiation dose techniques for clinical PET/CT scans through intra-individual comparison between a clinical, standard dose scan and a low-dose scan, completed within one week of each other.
- Detailed Description
Positron Emission Tomography/Computed Tomography (PET/CT) imaging using 18F-FDG is an important, commonly used cancer, neuroscience and cardio-vascular imaging methodology to detect disease and to monitor therapeutic interventions. While considerable technological progress of PET/CT systems has occurred over the last decade, we have not re-evaluated the ability to potentially reduce the radiation burden of the used PET imaging pharmaceutical (FDG).
This early phase trial intends to accomplish the following:
* to validate that the radiation dose burden from the PET imaging pharmaceutical (FDG) can be reduced by more than 50% from the current standard of clinical care (SOC) level without affecting the diagnostic ability;
* to confirm that a low dose approach will be feasible for response assessment;
* to validate that the difference in FDG uptake between imaging 60 min +/- 10 min post injection and 75 min +/- 10 min post injection is independent/equivalent of the injected FDG dose
* to validate a simulation methodology to streamline future dose finding studies for PET imaging pharmaceuticals.
