Summary

Computed tomographic (CT) guided biopsy is effective for skeletal lesions. This imaging technique provides accurate needle placement and minimizes radiation exposure for physicians during spinal and bone biopsies.

Area of Science:

  • Radiology
  • Interventional Radiology
  • Oncology

Background:

  • Computed tomographic (CT) guided biopsy and abscess drainage are established procedures for various organ systems.
  • Spinal and skeletal applications of CT guidance are less frequently reported in medical literature.
  • Accurate diagnosis of skeletal lesions often requires tissue sampling.

Purpose of the Study:

  • To describe the utility and safety of CT guidance for biopsy of diverse skeletal lesions.
  • To evaluate the application of CT guidance in spinal and appendicular skeletal biopsies.
  • To assess the effectiveness of CT-guided biopsy in a patient cohort with skeletal abnormalities.

Main Methods:

  • A retrospective analysis of 46 patients undergoing CT-guided skeletal biopsies.

  • Procedures included skinny needle aspirations (18 or 22 gauge) and trephine core biopsies.
  • Biopsy sites encompassed thoracic spine, lumbosacral spine, bony pelvis, ribs, and long bones.

    • Main Results:

    • CT guidance facilitated accurate needle placement within skeletal lesions.
    • The technique was applied to various spinal and extraspinal bone locations.
    • Physicians performing CT-guided procedures received minimal ionizing radiation due to precise visualization.

    Conclusions:

    • CT guidance is a valuable and safe tool for skeletal lesion biopsy.
    • The use of fast CT scanners enhances the feasibility of these procedures.
    • CT-guided biopsy offers precise targeting and reduced radiation exposure in skeletal interventions.
