A breast biopsy is performed to remove cells from a suspicious area in the breast and examine them to determine a diagnosis.
Stereotactic breast biopsy is an x-ray procedure that uses multiple coordinates to precisely determine the location of a tumor or nodule so that a tissue sample may be obtained.
In MRI-guided breast biopsy, magnetic resonance imaging is used to help guide the radiologist’s instruments to the site of the abnormal growth.
An ultrasound-guided breast biopsy uses sonic pulses to create images, rather than relying on low-dose radiation (as in a stereotactic biopsy) to do the same.
Image-guided needle biopsy is not designed to remove the entire lesion, but most of a very small lesion may be removed in the process of biopsy. Image-guided biopsy is performed when the abnormal area in the breast is too small to be felt, making it difficult to locate the lesion by hand (called palpation). With the help of some kind of imaging, your doctor will be better able to locate the lesion, thus ensuring the accuracy of the test.
