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.

Use of breast ultrasound:

• to evaluate a young (usually under 30 years of age) or pregnant patient who is symptomatic
• to evaluate a palpable lump with negative or equivocal mammographic findings
• detect lesions in lower contrast field
• can help to distinguish between benign vs malignant characteristics
• for guiding biopsy
• for evaluation of breast implants for rupture
