Automated whole-breast ultrasound (AWBU) is a technique that produces volumetric images of the breast and is largely independent of operator skill. It utilizes high-frequency ultrasound to help perform a diagnostic evaluation of the lactiferous ducts ( duct sonography ) [ 5 ] and make dilated ducts and intraductal masses visible.
Schematic image showing a woman undergoing a mammogram imaging examination. 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.
The entire breast is scanned in an automated manner, and the procedure yields volumetric image data of the breast. [1] The resulting image data can be read at any convenient time by the radiologist, who is freed from performing the scan. [2] This allows selected scan planes to be visualized, and also allows the data to be displayed as a ...

Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
A large multi-center breast imaging study has demonstrated both reproducibility [11] and significant improvement in the classification [12] of breast lesions when shear wave elastography images are added to the interpretation of standard B-mode and Color mode ultrasound images.
As with all X-rays, mammograms use doses of ionizing radiation to create images. These images are then analyzed for abnormal findings. It is usual to employ lower-energy X-rays, typically Mo (K-shell X-ray energies of 17.5 and 19.6 keV) and Rh (20.2 and 22.7 keV) than those used for radiography of bones.
A patient can expect to receive an injection of radiopharmaceutical agent intravenously in the arm contralateral to the breast under investigation. After waiting 5–10 minutes, the breast tissue is placed into the MBI system and a series of images are obtained. Imaging time for both breasts is approximately 40 minutes.
