Sonography competences liver/kidneys
Sonography, also known as ultrasound, is a form of examination in which sound waves are partially or completely reflected by tissue structures. The returning echo is first converted into an electrical signal at the transducer, which is used to create an image of the appearance of the internal organs. This works for the liver, gall bladder, pancreas, kidneys, urinary bladder, thyroid gland, as well as the large blood vessels. Unfortunately organs such as the stomach and intestines cannot be imaged using this method as they are filled with air and therefore do not produce suitable reflections. The more precise application opportunities of sonography for the liver and kidneys will be presented in this lecture.
