Abstract
In recent years, many different navigation and simulation technologies have been developed and are now being used in surgical operations and interventional radiology. At our hospital, we analyzed the data from the perfusion area of the target hepatic artery obtained using a cone beam CT during hepatic arteriography and during transarterial chemoembolization (TACE) using a commercially available 3-dimensional workstation and its software. This is called a virtual embolic area (VEA). We are exploring its use as a simulation during TACE. This article outlines the method of creating this VEA, and discusses and analyzes the accuracy of the VEA, current problems, future improvements, and future prospects for use in clinical practice.
