Radiation-Free Image Testing
Ultrasound, also known as sonography, is one of the few diagnostic imaging
procedures that does not use X-ray, making it the preferred testing method
for pregnant women.
Ultrasound uses sound waves to produce real-time moving images of soft
tissue and organs. It is routinely used to monitor fetus development during
pregnancy, and also to detect a wide range of conditions, including abnormal
growths, blood clots and disease.
What to Expect
An ultrasound is performed by a sonographer, who is specially trained in
this imaging procedure. The sonographer uses a device called a transducer,
a kind of wand, and covers the testing end of it with a water-soluble
gel to help ensure smooth contact between the transducer and the skin.
By moving the transducer over the body area being studied, high-frequency
sound waves are generated and the ultrasound unit translates those waves
Light and gentle pressure is used, and it's important that you lie
still during the exam and follow any instructions the sonographer gives.
Some ultrasounds require advance preparation, including drinking specific
amounts of water at certain intervals prior to your appointment, and some
may require you to fast prior to your exam. You'll be given instructions
in advance of your exam.
