How do the techniques of breast biopsy differ?

The goal of breast biopsy using different imaging techniques is the same, to obtain tissue from an area that is suspicious. Ultrasound guided biopsy can be performed with visualization of the area of abnormality using a hand held transducer. With monographic techniques we use what's called a stereotactic device where you are placed on a table with a special kind of imaging opening which allows us to then view the breast using mammography. Then the needle is then placed in a three-dimensional way so that we can strategically get into the area of abnormality without touching the remainder of the surrounding tissue. MRI guidance also provides the same kind of ability as mammography guidance however it's performed in conjunction with an MRI scanner.
