Background:Trans-arterial hemoembolization (TACE) usually indicated for unresectable hepatocellular carcinoma (HCC) on purpose as a bridging, downstaging or palliative treatment. Liver Imaging Reporting and Data Systems Treatment Response (LR-TR) was created to evaluate each lesion post-TACE, which has localized and is suitable for determining whether the tumor is still viable or Non-viable. Purpose: To assess the completion of LI-RADS version 2018 on computer tomography in the evaluation of HCC after TACE. Materials and Methods: A retrospective cross-sectional study involved 58 patients with hepatocellular carcinoma (HCC) who underwent treatment base TACE from June 2021 – September 2022. The clinical situation, AFP levels, and computer tomography (CT) of the patient after treatment were analyzed. The Radiologist evaluated pre- and post-treatment CT findings using LR-TR category, appropriately. The pooled sensitivity, specificity, and accuracy correclated between LR-TR with standard reference. Results: A total 58 patients with HCC (M/F: 13:1, mean age 56.9±11.0 years). For demonstrating the treatment response after first TACE on CT, Non-viable resulted in 32.8%(19/58), and LR-TR Viable was 67.2%(39/58), sensitivity value of 90% (36/40), specificity value of 83.3% (15/18), positive predictor value of 16.7% (3/18), a negative predictor value of 10% (4/40), accuracy value of 87.9% (51/58). The performance status response- AFP response- imaging response correlation was not statistically different, p= 0.552 and p=0.647. Conclusion: Using LR-TR on CT detects treatment response of HCC post-TACE was useful, and high sensitivity, specificity, and accuracy.
