Ultrasound imaging, also called
sonography, is a painless and noninvasive procedure
used to visualize the inside of the human body
through the use of high-frequency sound waves.
During an ultrasound, a trained
technician or doctor moves a device called a
transducer over part of your body; the transducer
emits sound waves, which bounce off tissues and are
received back as echoes. The echoes created can
identify the size, structure and location of body
tissues; that information is then used to create an
image on the area of study.
Ultrasound is the most utilized form
of diagnostic imaging after general x-ray, largely
because no radiation is involved, making it the
preferred imaging modality for diagnosis and
monitoring of pregnant women and fetuses.
It is also frequently used for
breast, cardiac, renal, liver, gallbladder, musculo-skeletal,
ophthalmic, testicle, salivary gland and lymph node
imaging among many others.
Additionally, ultrasound serves as a
guiding tool for interventional procedures such as
fine needle breast aspiration and biopsy
An exciting development in ultrasound
has been the development and increased use of 3-D
and 4-D ultrasound imaging, which gives
practitioners and parents an extremely detailed
picture of the unborn baby while in utero.
