An ultrasound is a non-invasive test that allows your doctor or radiologist to see inside your body. In this test, the size, shape and volume of the internal structures of the body can be seen well, which is very important for medical diagnosis. In this article, you will learn about the use of ultrasound, its preparation and how to perform it. Stay with us.
What is an ultrasound and how is it done?
Ultrasound is a medical diagnostic test that uses high-frequency waves (also known as ultrasound waves) to show an image of the inside of the body. In this test, the doctor observes problems with organs, blood vessels, and tissues without the need for surgery.
Unlike other shooting methods, this method does not use harmful rays. For this reason, it is used to see the fetus during pregnancy. The ultrasound sound waves are sent by a transducer and the computer converts these waves into images. In this way, the specialist identifies, measures and observes the components inside the image.
How to do it?
In most cases, you will need to lie on your back for this test, and the area to be tested should be exposed. The ultrasound technician will apply a colorless gel to your skin that prevents friction and also helps transmit sound waves.
The technician also soaks the head of the ultrasound machine in gel and then rubs it on your skin. Sometimes it is necessary to do this with pressure, which may be unpleasant. The device sends its ultrasound waves into your body, and these waves return when they hit a hard object, such as an organ or bone.
What is the purpose of this test?
Most people think that ultrasound is only for pregnancy. Although this test shows a very good view of the fetus, it has other uses as well. Your doctor may order an ultrasound if you have pain, swelling, or other symptoms that require you to see internal organs. If this is the case, this procedure is done to check for medical conditions:
- Uterine fibroids;
- Appendix rupture;
- Bulge in the testicle;
- Joint problems;
- Bulge in the chest;
- Ectopic pregnancy;
- Ovarian cysts;
- Bone diseases;
- Internal bleeding in the brain.
Ultrasound is also a guide for surgeons in biopsies and other medical operations. Its types are also used to diagnose these diseases:
- kidney stone;
- Liver disease;
- Abnormal limb size;
- Aneurysm or enlargement of the aortic artery.
Ultrasound during pregnancy
Ultrasound is most commonly used to monitor the growth of the uterus and fetus during pregnancy. The test is also used to determine the location, age and number of fetuses, and to identify possible birth defects.
Could it have side effects?
Ultrasound is a non-invasive imaging technique that poses no known risk. The waves of this experiment are completely harmless. Ultrasound is usually done on the surface of the skin. This test is not specifically prohibited and can be used by anyone. Although their sound waves can be destructive in the long run, the computer controls their power, and the radiologist minimizes the power of these waves by adjusting time and angle.
What do you need to know before your ultrasound?
- Keep in mind that you need to expose the skin of the ultrasound area, so wear comfortable clothing.
- It is best to arrive at the site a little earlier than the test time to have enough time to prepare.
- The test will take less than 30 minutes and will be performed in a hospital, imaging center or private office.
- Normally, you need to have a blood test before the ultrasound, but in an emergency, the medical procedure can be done without delay.
- You should ask your doctor before the test if you can drink water and food. If you have an ultrasound of your bile, the test should be done on an empty stomach and you should drink only fluids 6 hours before the test. If your bladder is being tested, you should drink plenty of water beforehand.
What happens after the test?
After the test, the gel is removed from your skin and you can leave the place without having to do anything special. The technician examines the created images for signs of health and illness. Once your doctor has examined the images, he or she will explain the final diagnosis and results to you.
