Liver ultrasound is a test that projects harmless ultrasonic waves to the liver, and reproduces the size and position information of reflectors caused by density differences between tissues as images. Ultrasonography of the liver can identify abnormal lesions of the liver. Doppler can track the flow of blood to the liver. Compared to computed tomography (CT) and magnetic resonance imaging (MRI), this is a useful test because it allows for interventional procedures such as drainage and biopsy of ascites and abscesses.
When is it necessary?
It is performed when interventional procedures such as drainage of the ascites or abscess, biopsy, and radiofrequency heat treatment are necessary when the detection and evaluation of liver masses, malignant tumors of the liver, and gallstones are necessary.
What is required?
Accurate testing can be difficult due to intestinal movement from food intake. Therefore, you should fast more than 8 hours before the test.
How does it work?
1. Examination is carried out in a lying position on the bed.
2. Jelly is applied to the area to be tested, and the ultrasound probe is rubbed in close contact with the skin.
3. Positioning of the diaphragm may be necessary to accurately view the liver, so breathing should be controlled as directed by the examiner.
4. Estimated travel time is about 5 to 15 minutes.
How do I check the test results?
After an accurate reading is made by the radiologist, you can hear the explanation of the test results from the medical staff.
What should I pay attention to?
When eating, fasting is required before the test, as the gastrointestinal tract may swell and cover the liver. It is also recommended to refrain from smoking cigarettes and gum as they can fill the air in your stomach.
In order to test the entire liver as much as possible, breathing control is required as directed by the examiner. At this time, when breathing in, the stomach comes out, and if you exhale, double breathing is effective.
