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."
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 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]
Schematic representation of a vacuum-assisted biopsy probe. Mammotome is a Cincinnati, Ohio–based company who pioneered a vacuum-assisted breast biopsy (VAC) device that uses image guidance such as x-ray, ultrasound and/or MRI to perform breast biopsies. A biopsy using a Mammotome® device can be done on an outpatient basis with a local ...
Molecular breast imaging (MBI), also known as scintimammography, is a type of breast imaging test that is used to detect cancer cells in breast tissue of individuals who have had abnormal mammograms, especially for those who have dense breast tissue, post-operative scar tissue or breast implants.

When consisting of calcium phosphate, they are usually dystrophic calcifications (occurring in degenerated or necrotic tissue). [3] Yet, the mechanism of their formation is not fully known. [4] Calcium oxalate crystals in the breast may be seen on mammography and are usually benign, but can be associated with lobular carcinoma in situ. [5]
