Ultrasound

An ultrasound machine uses high-frequency sound waves and a computer to create pictures of your body. You will have a special gel put on the skin where you are being scanned that helps conduct the sound. Then the technologist will move a wand that sends the sound waves around this same area. Ultrasound may be used externally or internally in the rectal or vaginal areas, depending on area being scanned. You will not feel or hear the high-frequency sounds the ultrasound machine makes. The images appear on a TV screen and are recorded. You may be asked to drink lots of water and wait to urinate until after the exam to improve the image.

St. John's utilizes the new GE LOGIQ 9 system which enhances imaging of soft tissue and bone structure. This system is used in obstetrics, abdominal imaging, gynecology and for other purposes. Expecting parents can see a truly round picture with even more detail of the fetus.
