Stereotactic Biopsy of the Breast
A stereotactic breast biopsy uses a specialized mammography device that employs ionizing radiation. This type of biopsy assists the radiologist to find the site of abnormal breast tissue growth.
Most of the time a conventional mammogram is sufficient, but in certain situations, a stereotactic biopsy may be necessary to find the exact spots for surgical removal.
What are these Special Situations?
- Small clusters of tiny calcium deposits
- a suspicious mass
- architectural distortions
- new growth in the area of a previous surgery
I just want to let you know that I have a new page all about breast biopsy, including Stereotactic Breast Biopsy.
When is this Biopsy necessary?
Stereotactic guidance is often used in core biopsy needle samples of suspicious breast
A computer combines two images at a ‘known’ angle of difference
Essentially, this type of breast biopsy is a stereo biopsy. So, as you would expect, on mammogram radiologists take two pictures. The images are at approximately 15 degrees angle difference (or some other known exact angle). A computer is then able to calculate the x, y and z position of any unique spot that is visible on both views.
The computer moves a little needle guide to the exact place. So when you insert a needle along the path of the needle guide, it ends up with the needle-tip at the correct location. In the days before there were computers moving robotic needle guides, there was a way to perform this biopsy with trigonometry and manual movement of needle guides.
This Breast Biopsy might avoid unnecessary breast surgery
