Automated tumor-feeder detection software (AFD) using computed tomography (CT) or cone-beam CT (CBCT) technology is a new tool of three-dimensional vessel-tracking. This software is now being used in transarterial targeted therapies, mainly transarterial chemoembolization (TACE) for hepatocellular carcinoma. We use TACE guidance software using CBCT data produced by Philips Healthcare (EmboGuide). The detectability rate of the tumor-feeder is 85-88% in the hepatic artery and 96% in extrahepatic arteries. This software can reduce our workload during the procedure, as well as procedural time and total doses of radiation exposure and contrast material. It can also extend the indications of TACE and improve the teamwork between medical staff members. Moreover, the TACE procedure can be standardized between institutions. Now, we are testing prototype virtual parenchymal perfusion (VPP) software (Virtual Injection) that can indicate a vascular territory corresponding to a virtual embolized area (VEA) on CBCT images according to a user defined catheter position. In our previous analysis, the VEA estimated using VPP showed a good correlation with the real embolized area of conventional TACE. Using this new functionality, further improvement of the technical success and outcomes of TACE are anticipated.
