ULTRASOUND IMAGING
Ultrasound
imaging, also called ultrasound scanning or sonography, is a method
of obtaining images from inside the human body through the
use of high-frequency sound waves. The reflected sound wave echoes
are recorded and displayed as a real-time visual image. No ionizing
radiation (x-ray) is involved in ultrasound imaging. Ultrasound
is a useful way of examining many of the body's internal organs,
including but not limited to the heart, liver, gallbladder, spleen,
pancreas, kidneys and bladder. Because ultrasound images are captured
in real time, they can show movement of internal tissues and organs
and enable physicians to see blood flow and heart valve functions.
Obstetric
ultrasound refers to the specialized use of sound waves to visualize
and thus determine the condition of a pregnant woman and her embryo
or fetus. The ultrasound can also estimate the age of the pregnancy,
diagnose congenital abnormalities, determine multiple pregnancies,
evaluate the position of the placenta and determine the amount
of amniotic fluid around the fetus.
PREPARATION AND SPECIAL INSTRUCTION
Instructions
will be given to you at the time of scheduling, whether by our
office or your physician. You should wear a loose-fitting two
piece outfit for the examination. For some ultrasound exams you
may require to drink water prior to the exam without voiding (urinating).
Some ultrasound exams may require that you not eat or drink the night before the exam.
WHAT TO EXPECT
Most
ultrasound examinations are painless, fast and easy. Ultrasound
examinations usually take less than 30 minutes. You will lie on
your back on an examining table. The technologist or doctor will
apply warm gel on your skin and press the transducer firmly against
your body, moving it until the desired images are captured. There
may be varying degrees of discomfort from pressure as the technologist
guides the transducer over the body part being imaged.
