Liver Ultrasonography To Capture Images Of The Liver

Ultrasonography uses sound waves to generate images. In patients with liver tumor, liver ultrasonography is suggested to locate and measure the size of a tumor and to determine if it is solid or cystic.

Ultrasound is often used during surgery and is called intraoperative ultrasound. This examination is performed on patients who undergo a surgical procedure on the liver. This imaging technique enables doctors to identify all of the tumors within the liver and clarify the relationship to blood vessels in the liver.

Liver ultrasonography is very useful to fatty changes in the liver. This is an inexpensive technique that does not expose patients to any radiation. If fatty changes are observed in more than 30 per cent of liver lobules, a diagnosis of fatty liver is done.

The Various Ultrasonic Features Of A Fatty Liver Are As Given Below:

  • Bright pattern
  • Vascular blurring
  • Deep attenuation
The sensitivity of liver ultrasound scans in the diagnosis of fatty liver is almost 100 per cent. The correlation of fatty liver in ultrasound scans and liver biopsy tissue examination is 73.6 per cent. So, the degree of fatty infiltration observed in ultrasound scans is significantly correlated with degree of fatty accumulation of liver.
During the test, a probe called a transducer is placed over the skin. The transducer sends out sound waves that pass through the body and are bounced back. The transducer receives the echoes and transmits them to a computer for further interpretation of the echo data as images of internal organs and tissues.
