Like CT scan, Magnetic Resonance imaging helps the doctor to place the core needle accurately in suspicious area to remove the small, cylindrical-shaped tissue sample.
The procedure requires only topical anesthetic application and it leaves little to no scaring.
Taking a breast biopsy guided in real-time by magnetic resonance (MR) imaging is the latest development and an important advance in diagnosing breast cancer.
MR-guided breast biopsy is usually a preferred alternative to surgical biopsy. This streamlines the diagnostic process and in some cases makes it possible to biopsy suspicious tissue that would otherwise have been very difficult to target.
It is used when ultrasound or mammogram (stereotactic) guided biopsy is not appropriate because the area of concern is not well seen by mammogram or ultrasound.
