CT-guided Thermal Ablation of Liver Tumors Using Intraprocedural CT-CT Fusion for Applicator Position and Ablation Completeness Assessment: a Single-Center Comparative Analysis.

ABSTRACT:

Purpose

To compare outcomes of CT-guided thermal ablation of liver tumors with versus without use of intraprocedural CT-CT image fusion.

Materials and methods

This retrospective cohort study included all patients treated with CT-guided percutaneous thermal ablation for hepatocellular carcinoma (HCC) or colorectal liver metastases (CRLM) between January 2017 and April 2023 at our institution. From October 2019, intraprocedural CT-CT deformable image fusion (IF) using dedicated software (Vitrea, Canon Medical) was introduced to the thermal ablation procedure workflow to visually assess applicator placement before ablation and ablation completeness posttreatment. Local tumor progression (LTP) was assessed on follow-up imaging. LTP-free survival (LTPFS) between groups with and w
