The Use of Breathing Synchronized CT and PET Scans in Radiation Therapy Treatment Planning
The Use of Breathing Synchronized CT and PET Scans in Radiation Therapy Treatment Planning

The purpose of this study is to find out whether a new device can help obtain more accurate CT and PET scans of the lungs and chest tumors and the liver and liver tumors to help in delivering radiation therapy. When we breathe, the amount of air in the lung changes. Lung tumors may also move during breathing. Liver tumors may also move with breathing; as the lungs inflate, the liver can be pushed down. A CT scan (a special type of X-ray) is routinely obtained as part of planning for lung or liver radiation therapy. Since patients breathe during this CT scan and their lung or liver tumors move, these CT scans can sometimes be inaccurate. We are now testing a device to only obtain the CT and an additional PET scan while patients are breathing in or out. This will hopefully allow us to deliver radiation with more accuracy.

The objectives are to measure the amount of tumor motion with respiration, measure changes in tumor definition with breathing synchronized PET compared to standard free breathing PET, and to determine the fraction of patients whose radiation treatment plans would be modified based on this information. Eligible patients are those receiving radiation treatment for thoracic or liver tumors.
