Role of MRI in assessment of hepatocellular carcinoma [HCC] after TACE [Trans-arterial Chemoembolization] with persistent high alfa fetoprotein [AFP]

ABSTRACT

Background: evaluation of treatment success after TACE is essential for making therapeutic decisions, e.g., to repeat, interrupt or completely terminate TACE. An understanding of the various therapeutic strategies and their post therapy imaging appearance is essential for accurately assessing treatment response. Evaluation of tumor response should include not only tumor markers, but also imaging modalities. Evaluation of the therapeutic effect of HCC after TACE is primarily based on the findings of imaging studies. CT is the standard imaging technique for monitoring the effectiveness of TACE. MRI is complementary to CT in the evaluation of the therapeutic response. To know the advantages and limitations of each imaging technique in the evaluation of the therapeutic effect of HCC is important in determining if the treated tumor is completely necrotic or requires additional treatment
