Diagnostic ultrasound is the use of high frequency sound waves to visualize structures within the body. A small device called a probe is used to send sound waves into the body, which are then reflected off of internal organs. The returning sound waves (echoes) are then sent back to the same probe and transformed electronically into images. If your blood flow is what is being studied, audible sound as well as an image can be produced.
Is ultrasound safe ?
Diagnostic ultrasound has been in use for over 25 years. The American Institute of Ultrasound in Medicine has issued the following statement in regards to the clinical safety of ultrasound: "No biological effects have been demonstrated on patients or instrument operators caused by exposure to ultrasounds as produced by current instruments. Although the possibility exists that such biological effects may be one day be identified, current data indicate that the benefits of the prudent use of diagnostic ultrasound outweigh the risks, that may be present."
Ultrasound manufacturers are constantly working to find additional ways to reduce exposure to ultrasounds without compromising diagnostic benefit.
Isn't ultrasound just for pregnancies ?
In addition to pregnancies, ultrasound is used to image all human body structures, except for bones and lungs. For example, we can examine the brain of children under one year of age. We can also test cervical structures, particularly the thyroid gland and carotid arteries, the heart, abdomen, pelvic cavity (uterus and ovaries), arteries and veins in limbs, and various musculoskeletal structures (except for bones). 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 ?
The procedure itself is painless. In order to obtain the best possible image, mild discomfort might occur from some pressure. A gel-like substance is applied to the skin surface so that the probe will have better contact. For some gynecological exams, it may be necessary to place the probe inside the vagina. |
