Breast ultrasound is also used to perform fine-needle aspiration biopsy and ultrasound-guided fine-needle aspiration of breast abscesses. [8] Women may prefer breast ultrasound over mammography because it is a painless procedure and does not involve the discomfort of breast compression present in mammograms.
With automated whole-breast ultrasound, the ultrasound transducer is guided over the breast in an automatic manner. The position and speed of the transducer is regulated automatically, whereas the angle of incidence and the amount of pressure applied is set by the human operator.
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 used as either a diagnostic or a screening procedure. [38] It may be used either with or without a mammogram. [39]

A suspicious area on mammography or ultrasound. [9] This may include: Microcalcifications on MRI. [10] BI-RADS score of 4 or 5 on mammography, ultrasound, or MRI. [11] A suspicious hard palpable lump [9] Skin changes like crusting, scaling, or dimpling of the breast, which may signal an underlying breast cancer [9] Abnormal nipple discharge [7] [9]
Acorn cyst sign is a radiologic sign indicating the presence of a benign uncomplicated cyst in ultrasound examinations of the breast. [1] It consists of a deep anechoic fluid portion resembling an acorn, and a superficial echogenic layer resembling an acorn cap. This sign is helpful for radiologists to differentiate a benign uncomplicated cyst ...
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
