Breast ultrasound imaging is performed with high-frequency transducers to produce dynamic examinations of all types of breast tissues. It is used as the preferred imaging modality in younger women (<40 years old) in the triple assessment of breast symptoms alongside clinical palpation and pathological assessment[23; 24]. In the older woman it is used as an adjuvant to other imaging modalities, especially mammography. Ultrasound can assess the size, shape and echotexture of lesions.
Breast cancer

Ultrasound imaging (sonography) of the breast uses sound waves to produce pictures of the internal structures of the breast. Breast ultrasound is primarily used for working up suspicious lesions that may have been found during a physical exam, from screening mammograms, or other imaging modalities. Thus, ultrasound is typically used to characterize a suspicious lesion (6).
Optimization and Dose Reduction in Mammographic Imaging

Breast ultrasound is another imaging procedure that does not involve exposure to ionizing radiation. Its greatest success in breast imaging is in differentiating cystic from solid masses. Ultrasound is also used for guidance of biopsy needles in the breast.

Breast density notification laws have been enacted in 38 states in the U.S. (as of March 2022) to mitigate the increased breast cancer risk in women with high breast density which is partially caused by the masking effect of dense breasts in screening mammography. These laws generally require physicians to notify patients with high breast density (classes 3 and 4) of their increased risk of breast cancer compared to women with low breast density. Moreover, in some states, the breast density notification law requires physicians to inform women with high breast density that adjunctive screening tests such as breast ultrasound and magnetic resonance imaging (MRI) may benefit them. Breast ultrasound uses high-frequency sound waves to make an image of breast tissue and as a result, has higher sensitivity than mammography in women with dense breasts. MRI uses intravenous contrast solution injection to produce 3-dimensional images of breast tissue.

The Radiological examination includes mammogram, breast ultrasound, MRI and Computerized Tomography (CT) scans. Mammogram is an X-ray examination screening technique to identify breast cancer. Using X-ray the pictures of the breast can be obtained. The breast ultrasound uses the sound wave to generate pictures of the breast. It is very helpful to determine whether the breast lump is solid or a cyst. During breast MRI, the magnetic radiofrequency pulses create a detailed picture of the inside of the breast. CT scan provides an image and pinpoints the abnormal location of the breast and determines the growth of cancer cells. The medical experts analyze the CT images and diagnosis cancer based on tumor shape, size and color [7].
