Imaging
Most commonly used imaging. Information from imaging: - Anatomic localization. - Vital structures. - Area most appropriate for biopsy. - Choice of technique.

Principles of biopsy
Performed. Minimize contamination. - Deep lesions.
- Approaches. - Healthy skin. - Biopsy tract. - Meticulous hemostasis: closed biopsy, open soft tissue and
bone.
Incision orientation.

Percutaneous technique
Core needle biopsy.
- Needle gauge. - Tissue sample and architecture. - Advantages. - Disadvantages. - Results.

Open techniques
Incisional biopsy:
- Gold standard. - Despite this fact. - Advantage. - Disadvantage. - Results.

Summary
Biopsy has a big impact. Biopsy plane. Closed biopsy techniques. Radiologist and pathologist. Physician performing the definitive
treatment.
