Summary
Brief summary (as posted)
This pilot study tests the pocket phantom tool in improving the accuracy of quantitative positron emission tomography/computed tomography (PET/CT) imaging of patients with solid tumors. The pocket phantom tool may help test the accuracy of the PET/CT scanner and indicate whether adjustments need to be made to get consistent information.

Arms and outcomes
Arms (1)
- label
- Diagnostic (PET/CT)
- description
- Patients undergo a PET/CT scan as part of their standard clinical care. While still positioned for the clinical scan, patients undergo additional research PET/CT scans in a smaller region over 10 minutes with the pocket phantom placed nearby and a low-dose single bed position CTAC.
- interventionNames
- Procedure: Computed Tomography
- Device: Imaging Phantoms
- Procedure: Positron Emission Tomography
Primary outcomes (1)
- measure
- Difference in measured versus known quantitative values of the pocket phantom
- timeFrame
- At day 1 (All data will be collected during the clinically scheduled appointment. Analysis will follow typical image reconstruction times.)
- description
- Compare measured activity of the pocket phantom (as measured by a PET/CT scanner) to the known values of the pocket phantom (as calculated based on half-life activity of known source) to determine accuracy and precision of scanner calibration. This will be used to validate quantitative clinical measurements, like SUV (standardized uptake values), of known solid tumors.
