Stereotactic Biopsy: What You Should Know
Ever been told you need a stereotactic biopsy and wondered why it’s different (and sometimes more costly) than an ultrasound biopsy?
Stereotactic biopsies are highly specialised procedures used when abnormalities (like microcalcifications) are only visible on a mammogram, not ultrasound. Using 3D mammographic guidance, the radiologist can precisely target and biopsy these tiny areas.
But what makes it so specialised?
- Advanced equipment and technique: The procedure relies on high-tech machinery, fine targeting, and a trained team.
- Time and precision: It often takes longer than an ultrasound biopsy due to positioning, targeting, and post-biopsy imaging.

- Sometimes two biopsies are needed: If your doctor identifies two separate areas, each will require its own sterile field, separate equipment, and careful repositioning. This is effectively two procedures in one -which is why the cost doubles.
Always ask if you’re unsure. Understanding the "why" behind your imaging journey empowers you to make informed decisions.
