An ultrasound test is a radiology technique, that uses high- frequency sound waves to produce images of organs and structures of the body. The sound waves are sent through body tissues with a device called a transducer. The transducer is placed directly on top of the skin, that has a gel applied to the surface. The sound waves which are sent by the transducer and are transmitted electrically on to a viewing monitor. The echo images are then recorded on a plane film and can also be recorded on video tape. After the ultrasound, the gel is easily wiped off.
Live Ultrasound Technical Term
The technical term for ultrasound testing and recording is "sonography". Ultrasound testing is painless and harmless. Ultrasound test involve no radiation and studies have not revealed any adverse effects.
Liver Ultrasound Purposes
Ultrasound examinations can be used in various areas of the body for a variety of purposes. These purposes include examination of the chest, abdomen, blood vessels (such as to detect blood clots in leg veins) and the evaluation of pregnancy. In the chest, ultrasound can be used to obtain detailed images of the size and function of the heart. Ultrasound can detect abnormalities of the heart valves, such as mistral valves prolapse, aortic steno sis, and infection (endocarditis). ultrasound id commonly used to guide fluid withdrawal (aspiration) from the chest, lungs or around the heart. Ultrasound is also commonly used to examine internal structures of the kidneys, the ureters, liver, spleen, pancreas, and aorta within the abdomen can be examined. Ultrasound can detect fluid, cysts, tumors or abscess in abdomen or liver.
Impaired blood flow clots or arteriosclerosis in the legs can be detected by ultrasound. Aneurysms of the aorta can also be seen. Ultrasound is also commonly used to evaluate the structure of the thyroid gland in the neck.
An abdominal or liver ultrasound plays a crucial role on diagnosing many liver diseases, including a fatty liver. To get accurate result, its very important to understand and know how you should prepare for a liver ultrasound.
Liver Ultrasound Preparation Guidelines
Do not drink or eat 6 hours before the test.
ON the day before the test do not eat - fresh fruits and vegetables, fired and oily food, milk, eggs, bread.
What you should eat - cooked vegetables, puree,marmalade, honey, roasted bread, soup, and rice
No medications are needed to be taken before Ultrasound
Liver Ultrasound scan is completely painless
Here is estimated procedure:
Lying on to an ultrasound table
A special gel will be spread upon your abdomen
The tester will move a tool called "transducer" (looks like a small wand) over the gel, that will create and capture the most relevant images.
The tester will process and look at the images, and will enter his conclusion
