Objectives: Evaluation of an amplitude based gated Positron Emission Tomography (PET) data acquisition system for all GE Discovery Positron Emission Tomography/ Computed Tomography (PET/CT) scanners.
Routine PET/CT scans are taken while patients are breathing normally. The motions made by breathing can reduce the image quality of the scan. Minimizing the effects of this motion by taking the images and processing the scans differently may improve the image quality. The PET/CT Scan: If you agree to take part in this study, an elastic belt will be placed around your lower chest/upper abdomen before your routine PET/CT scan. This belt is used to track your breathing motion. This information will be used to help process the scan. Your PET/CT scan will be performed as usual. During the scan, researchers will focus on your lower chest/upper abdomen (areas that experience breathing motion). Having to focus on this area might extend the scan by up to 10 minutes. The additional scan time will not increase your radiation exposure since only PET scanning will be performed. Length of Study: Your participation on this study will be complete when your scheduled PET/CT scan is complete. This is an investigational study. The imaging focused on your lower chest/upper abdomen during the scan is investigational. Up to 26 patients will take part in this study. All will be enrolled at M. D. Anderson.
