Summary
A novel coaxial drill system enables safe and accurate MRI-guided bone biopsies, even for dense lesions. This hand- or motor-powered system reliably obtains histological specimens, proving effective in clinical evaluations.
Area of Science:
- Medical Imaging
- Surgical Technology
- Orthopedic Oncology
Background:
- Percutaneous bone biopsy is crucial for diagnosing skeletal lesions.
- Existing systems may face challenges with dense or sclerotic bone.
- Advancements in imaging guidance are needed for improved biopsy accuracy.
Purpose of the Study:
- To develop and clinically evaluate a new MRI and CT compatible percutaneous bone biopsy system.
- To assess the system's performance in obtaining histological specimens from skeletal lesions.
- To determine the safety and reliability of the novel biopsy system.
Main Methods:
- A coaxial drill system, powered manually or by a pneumatic motor, was designed for MR-guided bone biopsies.
- The system was used in 23 patients undergoing biopsy procedures.
- Procedures were performed under 1.5 T MRI guidance (n=14) or CT guidance (n=9).
Main Results:
- The system provided safe and accurate MR-guided access to all tested lesions, including osteosclerotic ones.
- Percutaneous biopsy under MR or CT guidance yielded correct diagnoses in 18 out of 23 cases.
- No procedural complications were reported during the clinical evaluation.
Conclusions:
- The new coaxial drill system is safe and reliable for MR-guided percutaneous bone biopsy.
- The system effectively obtains histological specimens from skeletal lesions, even those with thick cortical or sclerotic bone.
- This technology offers a valuable tool for diagnosing bone pathologies.
