Intra-arterial Perfusion in Interventional Radiology

Patients are being asked to participate in a study to better determine blood flow going to tumors in the liver. They will undergo an embolization procedure in interventional radiology where the goal is to provide treatment directly into the liver tumor. These treatments are delivered into the blood vessels feeding the tumors. Improving these treatments relies on better understanding the blood flow into the tumor. By understanding how much blood flows into the tumors, the goal is to make sure there is the best chance of killing the tumor. The investigators are attempting to use a special type of CT scan during the procedure to determine the blood flow to the tumors.
