Safety Margin Assessment After RFA Using the Registration of Pre-ablation MRI and Post-ablation CT

HCC Clinical Trial

Official title:
Prospective Evaluation of Local Tumor Progression After Radiofrequency Ablation of Hepatocellular Carcinoma: Effectiveness of Immediate Second-Look Evaluation Using Pre-RFA MRI and Post-RFA CT Registration

Clinical Trial Summary

Magnetic resonance imaging (MRI) has been widely used for small liver lesion detection and characterization. In patients who undergo RFA, MRI is often performed before RFA, whereas immediate technical success is usually assessed by CT. Conventional visual assessment of two modalities may be more challenging than being anticipated, because acquisition position, respiration, and spatial resolution differ between the two. Therefore, the study purpose is to evaluate the results of software-assisted ablative margin assessment using registration of different pre-and post-RFA modalities compared with the conventional method of side-by-side MRI-CT comparison in patients with HCCs.
