Area of Science:

  • Hepatobiliary imaging and intervention
  • Interventional radiology
  • Diagnostic pathology

Context:

  • Percutaneous liver biopsy is essential for diagnosing liver tumors.
  • Ultrasound (US)-guided biopsy is a primary, safe, and effective method.
  • Lesion visibility and accessibility often dictate the choice of imaging guidance.

Purpose:

  • To review the indications and techniques for image-guided liver biopsy.
  • To compare different imaging modalities (US, CT, MRI) for liver lesion biopsy.
  • To highlight the shift towards core biopsy for improved classification.

Summary:

  • Ultrasound-guided biopsy is standard for liver lesions, with CT and MRI used when US is insufficient.
  • Hepat-specific contrast agents can enhance delineation of tumor tissue.

  • Transvenous biopsy is an alternative for diffuse liver disease when percutaneous biopsy is contraindicated.
  • Coaxial core biopsy has largely replaced fine-needle aspiration, offering a safe and efficient method with low complication rates.

    • Impact:

    • Provides a comprehensive overview of current image-guided biopsy techniques for liver lesions.
    • Informs clinical decision-making regarding the optimal biopsy approach based on lesion characteristics.
    • Emphasizes the safety and efficacy of modern core biopsy techniques in liver tumor classification.
