Ultrasound at Cheyenne Radiology & MRI


Ultrasound

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 then sent back to the same transducer and the attached equipment electronically changes the echoes into a picture (image) of your internal structures. If your blood flow is being studied, audible sound as well as an image can be produced


IS ULTRASOUND SAFE?

Diagnostic ultrasound has been in use for over 30 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." Even with these precautions in place, ultrasound manufacturers are constantly working to find additional ways to reduce ultrasonic exposure without compromising diagnostic benefit.

ISN'T ULTRASOUND JUST FOR PREGNANCIES?

Besides pregnancies, ultrasound is used 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 your 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.

WILL ULTRASOUND HURT?

Ultrasound procedures are painless, but in order to obtain the best image possible, mild discomfort might occur from some pressure or angling in an unusual direction. A gel-like substance is applied to the skin surface so that the transducer will have better contact; the gel might be slightly cold but it will not be painful. For some OB and gynecological exams, it may be necessary to place the transducer inside the vagina, however most women do not find this uncomfortable. In the case of a prostate exam, a transducer is inserted into the rectum; this will not cause any more discomfort than a normal rectal examination
