What is an ultrasound:
Ultrasound is used in medicine to visualize human body parts, organs and for studying defects in their structure. Ultrasound uses high frequency, called ultrasound. The waves are translated and converted to images displayed on a screen and recorded. This way images can be printed. Today, these devices give high quality images and some even allow visualization of bodies in three dimensions (3D ultrasound).
How does ultrasound work:
Ultrasound consists in passing a probe over the skin.The probe sends ultrasound that are reflected by different tissues found in its path. The images are then transmitted to a computer screen. Probes are different depending on the organ to be studied. An aqueous gel is used, which facilitates the contact with the skin or mucous membrane . Ultrasound is generally practiced on the patient lying on his back. This exam is completely painless and has no contraindication. Using ultrasound is used in obstetrics – gynecology and also can be studied and other organs, such as the gallbladder, liver, thyroid, lymph, and musculoskeletal system – the muscles, joints, tendons, ligaments. Ultrasound is also a method of investigation and examination of male genitalia. Ultrasound is using a contrast agent. This substance is injected into the veins a few minutes before the exam. This method is mostly used for examination of the liver, and brain arteries.
