Interventional radiology, using computed tomography (CT) and sonography, enables safe and effective percutaneous biopsies and abscess drainages. These minimally invasive procedures offer high accuracy rates and low complication risks, becoming standard in many healthcare settings.

Area of Science:

  • Interventional Radiology
  • Medical Imaging
  • Minimally Invasive Procedures

Background:

  • Interventional radiology has advanced significantly due to computed tomography (CT), sonography, and improved techniques.
  • CT and sonography provide detailed anatomical information crucial for interventional procedures.
  • Percutaneous biopsies and abscess drainages are increasingly common and vital diagnostic and therapeutic tools.

Purpose of the Study:

  • To review the indications, accuracy, and complications of percutaneous biopsies and abscess drainages.
  • To highlight the safety and efficacy of CT-directed interventional procedures.
  • To discuss the expanded applications of percutaneous drainage techniques.

Main Methods:

  • Review of percutaneous biopsies guided by CT and sonography.

Related Experiment Videos

  • Analysis of CT-directed percutaneous abscess drainage techniques.
  • Evaluation of indications, accuracy rates, and complication profiles for both procedures.

    • Main Results:

    • Percutaneous CT-directed biopsies achieve accuracy rates exceeding 90% with low complication rates.
    • CT-directed percutaneous abscess drainages are safe, effective, and often preferred over surgical interventions.
    • Indications for percutaneous drainage have expanded beyond simple fluid collections to complex abscesses and procedures like cholecystotomies.

    Conclusions:

    • Percutaneous biopsies and abscess drainages are highly accurate and safe interventional radiology procedures.
    • CT and sonography have revolutionized the performance and applicability of these minimally invasive techniques.
    • These procedures offer significant advantages in diagnosing masses and treating abscesses, with expanding clinical utility.
