Summary
Brief summary (as posted)
The purpose of this study is to see if it is possible to establish a relationship between the blood flow and blood volume of liver tumors from CT body perfusion and the radiation dose deposited in the tumors from the radioembolization treatment as measured by PET/CT. The study will do this by: 1. Measuring the blood flow and blood volume of tumors in the imaging data from a CT body perfusion 2. Measuring the radioactivity in the tumors after the radioembolization treatment using PET/CT and then calculating the dose deposited in the tumor 3. Using statistical analysis to assess the relationship between the dose and the perfusion parameters In addition, the research may help develop a method for calculating the dose of radioembolization to be delivered to a liver tumor(s) using blood volume and blood flow data obtained from the CT body perfusion scans.
