    This study compares local tumor progression rates after ultrasound-guided thermal ablation with and without intraprocedural CT control.

  • 2

    The research was conducted at a single tertiary hepatobiliary center from January 2018 to December 2021, focusing on colorectal liver metastases.

  • 3

    Patients underwent ablation with curative intent, with treatment allocation based on tumor localization and visibility.

  • 4

    The study found that intraprocedural CT control may improve margin assessment and reduce local tumor progression compared to ultrasound alone.

  • 5

    Findings emphasize the importance of imaging guidance in achieving adequate ablative margins and optimizing treatment strategies.
