Stereotactic biopsy is done with the help of a specialized device, which provides mammographic guidance. For a stereotactic biopsy, morbid obesity is a relative contraindication due to weight limitations of the devices. Pregnancy and breast compression size may also be contraindications depending on the modality being used. [15]
Stereotactic biopsy, also known as stereotactic core biopsy, is a biopsy procedure that uses a computer and imaging performed in at least two planes to localize a target lesion (such as a tumor or microcalcifications in the breast) in three-dimensional space and guide the removal of tissue for examination by a pathologist under a microscope.
The "Egan technique", as it became known, enabled physicians to detect calcification in breast tissue; [68] of the 245 breast cancers that were confirmed by biopsy among 1,000 patients, Egan and his colleagues at M.D. Anderson were able to identify 238 cases by using his method, 19 of which were in patients whose physical examinations had ...
Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.

Dystrophic calcification (DC) is the calcification occurring in degenerated or necrotic tissue, as in hyalinized scars, degenerated foci in leiomyomas, and caseous nodules. This occurs as a reaction to tissue damage, [ 1 ] including as a consequence of medical device implantation.
A newer type of breast biopsy technique is the stereotactic biopsy which relies on a three-dimensional X-ray to guide the needle of non-palpable mass. The biopsy is performed in a similar manner, by using a needle to remove a tissue sample, but locating the specific area of the breast is done by X-raying the breast from two different angles.
When horizontal x-ray beams, commonly used in lateral projections, are used to image the breast, the fluid inside the cysts, such as milk of calcium, is imaged tangentially. [2] This technique often produces linear or curvilinear patterns of calcification. In some cases, a semilunar shape may appear, which is why this sign is called "teacup sign."
