    A novel computed tomography (CT)-assisted biopsy technique using a grid reference system and lasers offers a simple, fast, and reproducible method for lung and abdominal biopsies.

    Area of Science:

    • Medical imaging
    • Interventional radiology
    • Surgical techniques

    Background:

    • Traditional biopsy methods can be limited by accuracy and procedure time.
    • Computed tomography (CT) offers detailed anatomical visualization.
    • Need for improved accuracy and efficiency in image-guided biopsies.

    Purpose of the Study:

    • To describe a novel CT-assisted biopsy technique.
    • To evaluate the efficacy and advantages of this new method.
    • To compare CT thoracic biopsy with conventional fluoroscopy.

    Main Methods:

    • A CT-assisted biopsy technique utilizing a grid reference system and light lasers was developed.
    • The technique was applied to 10 lung biopsies and 13 abdominal biopsies.
    • Procedure simplicity, speed, and reproducibility were assessed.
