Ultrasound is a non-invasive technique that is used to diagnose what is happening in the body, based on images that the device is taking. By means of sound waves ─hence its name─, which are above the human threshold, it emits frequencies in which the images of the body’s organs are recreated.
Ultrasounds, in general, are placed on the patient’s skin to diagnose the state of the organs; however, there are some that can be located inside the body, such as those that are made of the digestive tract, vaginal or blood vessels.
But what is the use of an ultrasound?
As we have said, ultrasound emits sound waves to produce photographs or images of the body’s organs. Its effectiveness is high because it helps to diagnose causes of pain, if the patient has swelling that has not been detected otherwise, or if there is an infection.
In pregnant women, ultrasound is effective in viewing the fetus and its stage within the mother. Ultrasound has also been shown to be effective in evaluating the brain and skeletal system of children. In addition, ultrasound is a complement to biopsies and the status of the heart.
Benefits of ultrasound
Having an ultrasound is a safe procedure. As it is non-invasive, it does not require extensive patient preparation, which reduces the fear of performing it. On the other hand, it is a massive procedure and can be carried out frequently; there are no restrictions.
Similarly, the images provided by ultrasound are very safe; This procedure does not use radiation and the pictures it takes are easy for the treating doctor to read. Ultrasound is a quick procedure.
When performing an ultrasound, you will be able to see, thanks to the photographs, the soft tissues, which is an advantage over traditional X-ray images. The images are taken in real time while the procedure is being carried out.
For pregnant women, ultrasound is one of the safest methods of observing the fetus because it does not affect its development.
