Abstract: Objective The aim of this study was to investigate the early evaluation of complete inactivation of tumors by contrast enhanced ultrasound (CEUS) and enhanced magnetic resonance imaging (MRI) scan after radiofrequency ablation (RFA) in patients with primary liver cancer (PLC). Methods 81 patients with PLC were encountered in our hospital between January 2019 and January 2022, and all underwent RFA. One month after the treatment, the CEUS and enhanced MRI scan were performed, and the consistency with digital subtraction angiography (DSA), as the gold standard was compared. Results Out of the 81 patients with PLC, the DSA examination showed the tumor foci was completely inactivated in 61 cases, with tumor residual in 20 cases; the sensitivity (Se), specificity (Sp) and accuracy (Ac) by CEUS evaluation were 91.8%, 85.0% and 90.1%, the Se, Sp and Ac by MRI scan were 96.7%, 95.0% and 96.3%, and the Se, Sp and Ac by CEUS and MRI combination evaluation were 98.4%, 100.0% and 98.8%. Conclusion The early evaluation of tumor inactivation by CEUS and enhanced MRI scan combination after RFA treatment in patients with PLC is efficacious, which might guide the clinicians to make appropriate measures for better outcomes.
