In medicine, breast imaging is a sub-speciality of diagnostic radiology that involves imaging of the breasts for screening or diagnostic purposes. There are various methods of breast imaging using a variety of technologies as described in detail below.
Traditional screening and diagnostic mammography uses x-ray technology. Breast tomosynthesis is a new digital mammography technique that produces 3D images of the breast using x-rays. Xeromammography and Galactography also use x-ray technology and are also used infrequently in the detection of breast cancer. Breast ultrasound is another technology employed in diagnosis & screening and specifically can help differentiate between fluid filled and solid lumps that can help determine if cancerous. Breast MRI is, yet, another technology reserved for high-risk patients and can help determine the extent of cancer if diagnosed.
HMI utilizes state-of-the-art digital mammography, shown to be more accurate than film screen mammography among women under the age of 50 years, women with heterogeneously dense or extremely dense breasts on mammography, and premenopausal or perimenopausal women.
