Most people think that ultrasonography is used only in the diagnosis and/or treatment of internal organs. What they don’t know is that this piece of medical technology can also be used on musculoskeletal disorders.
An ultrasound machine is used in ultrasonography, which is basically the use of an imaging modality that utilizes high frequency sound waves to visualize international structures of the human body. This imaging technique is similar to the echolocation used by animals such as bats, dolphins, and whales, as well as SONAR used by submarines.
The ultrasound machine works by transmitting high frequency sounds that the average person can’t usually hear into the body via a probe. Then, these sound waves travel inside the body and hit a boundary between tissues. Some of the sound waves get reflected back to the probe, while others travel further until they reach another boundary and get reflected and relayed back to the machine.
Then, the machine will calculate the distance between the probe and the tissue using the speed of sound in the tissue and the time of each echo’s return. It will display the distances and intensities of the echoes on the screen to form an image, allowing the doctor to see what’s inside your body, including your tendons, muscles, and ligaments.
Ultrasound can be quite useful in the detection and treatment of chronic pain. Aside from the fact that it is convenient and has a high efficiency rating, it is non-invasive, as well. It won’t cost you pain and it is free from radiation. It is also a huge help to patients because getting an ultrasound is not that expensive as compared to MRI.
