CT-Guided Trans-osseous Biopsy: Experience in 24 Patients

Area of Science:

• Radiology
• Interventional Radiology
• Oncologic Imaging

Background:

• Deep-seated lesions often pose diagnostic challenges.
• Conventional biopsy methods may be limited by anatomical location or proximity to vital structures.

Purpose of the Study:

• To evaluate the efficacy of computed tomography (CT)-guided trans-osseous biopsy for deep-seated lesions.
• To document complications associated with this minimally invasive procedure.

Main Methods:

• Retrospective cohort study of 24 patients with deep-seated lesions.
• Trans-osseous biopsy performed via sternum, vertebrae, iliac, scapula, rib, sacrum, and pubis.
• Exclusion of cases amenable to simpler biopsy techniques.

Main Results:

• Procedure efficiency was 87.5%.
• 8.33% of biopsies were non-diagnostic.
• 4.17% were inconclusive due to procedural vital risk.

Conclusions:

• CT-guided trans-osseous biopsy is a safe and effective technique.
• This method is particularly useful for lesions obscured by vital structures or otherwise inaccessible.
