What is an ultrasound?

An ultrasound is a medical test that permits your doctor to capture live images from your insides, which is helpful to diagnose any condition you might have, or for pregnant women, it allows them to know the status and health of the baby.

An ultrasound scan is used to visualize your organs, vessels, and tissues without using a scalpel and with zero pain. Also, the good thing about this exam is that it does not use radiation to penetrate your skin. In the next section, we will further explain the functioning of this exam.

How does an ultrasound work?

Ultrasound images are produced by high-frequency waves that will create an image of the inside of your body.

The reason why an ultrasound does not need any radiation is that it works with sound waves. It is also known as sonography, and it transmits the sound waves to the body and on the monitor, you will see the waves that echo back.

It is a versatile tool that is not invasive and allows you to see in real-time what is going on inside your body. It is mainly used to keep track of your pregnancy, or it can also be used to diagnose pain, swelling, or other symptoms, in about 15 to 45 minutes!

What types of ultrasound exist?

The main types of this scan are

  • External ultrasound scan. It is the most popular type of this exam, it can be used to check an unborn baby, or to examine the liver, kidneys, and some other organs and tissues. A lubricating gel is needed to move the probe smoothly.
  • Internal ultrasound scan. This type of scan will let you take a look at the inside of some organs, like the prostate gland, ovaries, or womb. This type of scan will cause some discomfort, but it will be done rapidly.
  • Endoscopic ultrasound scan. For this type of ultrasound, an endoscope goes through your mouth until it reaches your stomach. It permits you to examine different areas of your stomach and esophagus.
