Summary
This summary is machine-generated.

Percutaneous biopsies, including ultrasound-guided fine-needle aspiration (FNA) and core-needle biopsy, are crucial for diagnosing focal lesions when advanced imaging like CT, sonography, and MRI are inconclusive. These minimally invasive procedures significantly impact patient treatment decisions.

Area of Science:

  • Radiology and Medical Imaging
  • Interventional Procedures
  • Pathology Diagnostics

Background:

  • Advanced cross-sectional imaging (CT, sonography, MRI) enables non-invasive evaluation of parenchymal organs and pathological changes.
  • Despite high refinement, imaging alone often cannot definitively distinguish between benign and malignant focal lesions.
  • Accurate diagnosis of focal lesions is critical for appropriate patient management.

Purpose of the Study:

  • To present experience with over 10,000 percutaneous biopsy interventions across various organs.
  • To discuss the techniques, outcomes, challenges, and risks associated with percutaneous biopsies.
  • To highlight the impact of biopsy results on patient treatment strategies.

Main Methods:

  • Ultrasound-guided fine-needle aspiration biopsy (FNA).

Related Experiment Videos

  • Core-needle biopsy, including high-speed and vacuum-assisted techniques.
  • Percutaneous interventions guided by imaging modalities.

    • Main Results:

    • Percutaneous biopsies are essential for characterizing focal lesions when imaging is indeterminate.
    • Over 10,000 interventions were performed, providing extensive procedural experience.
    • Biopsy results frequently alter patient treatment plans, particularly for lymphomas, pancreatic carcinomas, breast cancers, and recurrent tumors.

    Conclusions:

    • Percutaneous biopsy remains a cornerstone in the etiological diagnosis of focal lesions.
    • The integration of advanced imaging and biopsy techniques optimizes diagnostic accuracy.
    • Biopsy-driven treatment modifications significantly improve patient outcomes in various oncological and hematological conditions.
