Ultrasonography of the breastHow the Test is Performed
You will be asked to undress from the waist up and put on amedical gownduring the test. During the test, you will lie on your back on the examining table.
A water-soluble gel is placed on the breast and a hand-held device (transducer) that directs thesound waves to the breast tissue. The transducer ismoved over the surface of the breast to create a picture.
The test is then repeated for the other breast, if necessary.
How to Prepare for the Test
Since you need to remove your clothing from the waist up, it may be helpful to wear a two-piece outfit. On the day of the test, do not use any lotions or powders on your breasts.
How the Test Will Feel
The number of people involved in the test will be limited to protect your privacy.
You will be asked to raise your arms above your head and turn to the left or right as needed.
There is no discomfort from the ultrasound device.
Why the Test is Performed
Breast ultrasonography may be used with mammography or by itself.
Ultrasonography may be used to detect and classify breast lesions in the following types of women:
- Women with dense breasts
- Women with fibrocystic breast disease
- Women with a lesion that cannot be well classified with mammography alone
- Young women with masses
- Pregnant women with masses
- Women with silicon breast implants
- Women who refuse exposure to x-rays (mammography)
Normal Results
Normally, the breast tissue will appear uniform and without masses.
What Abnormal Results Mean
Distinctive patterns may indicate:
- Cysts
- Benign lesions
- Malignant lesions (breast cancer)
