Breast ultrasound examination produces images of your breast using inaudible
sound waves in a frequency range far above the range of human hearing.
This procedure also is known as a sonogram. A breast ultrasound may be
ordered by your physician or recommended by your radiologist to obtain
more information about a possible abnormality. It is frequently done to
assess the characteristics of a lump.
What to Expect
The examination will be performed by a technologist who is an expert in
using ultrasound. A hypo-allergenic, water-soluble gel will then be applied
to your breast to prevent air from getting between the ultrasound source
and your skin. A small probe, called a transducer, will be passed over
the surface of your breast, producing a painless sensation of light pressure
on your skin. The exam typically takes about 15 to 30 minutes.
The examination results will be evaluated by a radiologist skilled in
interpreting sonograms. The results will be sent to your referring physician
within five working days.
