Ultrasound imaging, also called ultrasound scanning or sonography,
involves exposing part of the body to high-frequency sound waves to
produce pictures of the inside of the body. Ultrasound exams do not
use ionizing radiation (as used in X-rays). Because ultrasound images
are captured in real-time, they can show the structure and movement of
the body's internal organs, as well as blood flowing through blood vessels.
Ultrasound imaging is a noninvasive medical test that helps doctors
diagnose and treat medical conditions.
Ultrasound imaging of the breast produces a picture of the internal
structures of the breast. Doppler ultrasound is a special ultrasound
technique that evaluates blood as it flows through a blood vessel,
including the body's major arteries and veins in the abdomen, arms,
legs and neck.
During a breast ultrasound examination, the sonographer or doctor
performing the test may use Doppler techniques to evaluate blood flow
or lack of flow in any breast mass. In some cases, this may provide
additional information as to the cause of the mass.
