Ultrasound at
Pennsylvania Hospital
Ultrasound (also called ultrasonography) is
a way for doctors and medical personnel to look
at or image the body. Instead
of radiation, ultrasound uses sound waves to
provide an internal image (called a sonogram)
of the body. The procedure is safe for patients
and when used during pregnancy, for fetuses in
the womb. The use and technique
of ultrasound depends on which organ is being
viewed. Therefore
preparation instructions from your provider may
vary.
Ultrasound takes pictures of different “sections" or "slices” throughout
the body by using a probe (transducer) which
slides over the skin. Ultrasound
can also be used to check blood flow and blood
vessels by using the Doppler technique. This
technique is also safe for patients.
All the images taken during ultrasound are displayed
on monitors for the patients to view instantaneously
and are filed on disk or film for future access
if needed.
