    Colorectal cancer is the most common gastrointestinal malignancy, with the liver as the primary site of metastases in 30%-50% of patients.

  • 2

    Current imaging practices for evaluating tumor progression after treatment include contrast-enhanced CT and serum CEA, but have limitations in accuracy.

  • 3

    Adding [18F]FDG-PET/CT to CECT may improve tumor detection by revealing metabolic activity that is not visible on morphological imaging alone.

  • 4

    The study analyzed the diagnostic value of [18F]FDG-PET/CT in patients with colorectal liver metastases following thermal ablation or resection.

  • 5

    The first follow-up imaging after local treatment was conducted 3-5 months later, combining CECT with [18F]FDG-PET/CT to assess recurrence.
