Impact of C-arm CT in Patients With HCC Undergoing TACE: Optimal Imaging Guidance

We hope to learn more about the utility of C-arm CT in patients undergoing TACE for HCC. Data will be evaluated with regards to: 1. Sensitivity and specificity to diagnose additional tumors and its impact on transplantation criteria. 2. The ability to decrease procedural time by aiding navigation through complex arterial anatomy. 3. Impact on radiation dose. Although the patient would receive the radiation during C-arm CT, overall the number of DSA angiograms and fluroscopy may decrease, potentially negating any effect of the additional dose from C-arm CT
