Breast ultrasound
Breast Ultrasound
Breast ultrasound (pronunciation: /ˈbrɛst ˌʌltrəˈsaʊnd/) is a medical imaging technique used to assess the internal structures of the breast. It is often used as a follow-up test after an abnormal finding on a mammogram or clinical breast exam.
Etymology
The term "ultrasound" is derived from the Latin words "ultra" meaning beyond, and "sound". This is because ultrasound uses sound waves that are beyond the range of human hearing to create images of internal body structures.
Procedure
During a breast ultrasound, a healthcare provider applies a water-based gel to the breast and then moves a handheld device called a transducer over the area. The transducer emits sound waves that bounce off the breast tissue and create echoes. A computer then translates these echoes into images on a screen.
Uses
Breast ultrasound is used to:
- Evaluate abnormal findings on a mammogram or clinical breast exam
- Distinguish between solid masses and fluid-filled cysts
- Guide biopsy procedures
- Monitor existing benign breast conditions
- Screen for breast cancer in women with dense breast tissue
