In medicine, breast imaging is the representation or reproduction of a breast's form. There are various methods of breast imaging such as:
- Mammography is a specific type of breast imaging that uses low-dose x-rays to detect cancer early—before women experience symptoms—when it is most treatable. Mammography plays a central part in the early detection of breast cancers because it can show changes in the breast up to two years before you or your physician can feel them.
- Digital breast tomosynthesis (DBT) can provide a higher diagnostic accuracy compared to conventional mammography. In DBT, like conventional mammography, compression is used to improve image quality and decreases radiation dose. The laminographic imaging technique dates back to the 1930s and belongs to the category of geometric or linear tomography.
- Xeromammography is a photoelectric method of recording an x-ray image on a coated metal plate, using low-energy photon beams, long exposure time, and dry chemical developers. It is a form of xeroradiography.
- Breast MRI, an alternative to mammography, has shown substantial progress in the detection of breast cancer. The available literature suggests that the sensitivity of contrast-enhanced breast MRI in detection of cancer is considerably higher than that of either radiographic mammography or ultrasound and is generally reported to be in excess of 94%
- Breast ultrasounds may be used with or without a mammogram. Breast ultrasound is the use of medical ultrasonography to perform imaging of the breast. It can be considered either a diagnostic or a screening procedure. It may be used either with or without a mammogram.
- Scintimammography is a type of breast imaging test that is used to detect cancer cells in the breasts of some women who have had abnormal mammograms, or for those who have dense breast tissue, post-operative scar tissue or breast implants, but is not used for screening or in place of a mammogram. Rather, it is used when the detection of breast abnormalities is not possible or not reliable on the basis of mammography and ultrasound.
