    Area of Science:

    • Medical Imaging
    • Surgical Technology
    • Interventional Radiology

    Background:

    • Percutaneous needle biopsy is crucial for diagnosing abdominal masses.
    • Traditional biopsy methods can be limited by accuracy, cost, and radiation exposure.
    • Real-time imaging guidance is essential for precise needle placement.

    Observation:

    • A novel system integrates a real-time ultrasonic transducer with a steerable needle holder.
    • Simple trigonometric functions were used to create a guidance chart for needle angulation and length.
    • The system facilitates dynamic, real-time ultrasonic guidance during biopsy procedures.

    Findings:

    • The method successfully obtained cytologic and histologic specimens from abdominal masses.
    • Successful biopsies were demonstrated in renal, hepatobiliary, and retroperitoneal regions.
    • The technique ensures quick, reliable, and accurate guided needle placements.

    Implications:

    • This technique offers a faster, more accurate, and cost-effective alternative for percutaneous biopsies.
    • The 3D format and omission of contrast media and radiation enhance patient safety and reduce procedural complexity.
    • This method has the potential to improve diagnostic yield and patient outcomes in abdominal mass biopsies.
