A1. Diagnostic ultrasound is the use of high frequency sound waves to visualize structures within the body. A small device called a transducer is used to send sound waves into the body, which are then reflected off of internal structures. The returning sound waves (echoes) are captured by the same transducer and sent to the attached equipment which electronically changes the echoes into a picture (image) of the internal structures. Some equipment can produce audible sound from the echoes. This is helpful in the study of blood flow and the fetal heart. (Back to Top )
Q2. Is Ultrasound Safe?
A2. Diagnostic ultrasound has been in use for over 35 years. The American Institute of Ultrasound in Medicine has issued the following statement in regards to the clinical safety of ultrasound:
"No confirmed biological effects on patients or instrument operator caused by exposure at intensities typical of present diagnostic instruments have ever been reported. Although the possibility exists that such biological effects may be identified in the future, current data indicate that the benefits to patients of the prudent use of diagnostic ultrasound outweigh the risks, if any, that may be present."
Ultrasound manufacturers are constantly working to find additional ways to reduce ultrasonic exposure without compromising diagnostic benefit. (Back to Top )
Q3. Will Ultrasound Hurt?
A3. The ultrasound procedure itself is painless, but in order to obtain the best image possible, mild discomfort might occur from the pressure or angling being used by the sonographer to acquire the images. A gel-like substance is applied to the skin surface of the tummy, so that the transducer will have better contact; the gel might be slightly cold but not painful.
For keepsake exams, the transducer is used on the tummy, exclusively.
For diagnostic exams, the transducer is usually used on the tummy. However, for some diagnostic exams, it may be necessary to place a specially designed transducer inside the vagina, however most women do not find this uncomfortable. (Back to Top )
Q4. Is Ultrasound Just for Pregnancies?
A4. Ultrasound is used on men and women of all ages to image the gallbladder, liver, kidneys, pancreas, uterus, ovaries, prostate, testicles, thyroid and breasts. Ultrasound can also look at and listen to the blood flow within arteries and veins in the neck, abdomen and legs and the valves and chambers of the heart. Additionally, ultrasound is becoming increasingly important in surgery as a visual aide to the surgeon. Ultrasound is one of the most quickly growing diagnostic tools. Clinicians around the world are constantly finding new applications for ultrasound systems.
