Ultrasonography of the liver is a type of ultrasonography of the abdomen.

Planning

Contrast-enhanced liver ultrasonography is often indicated in cases of focal liver changes, as well as follow-ups of metastases. In Swedish practice, it should be performed within 2 to 4 weeks, depending on the supiciousness of cancer.

Ultrasonography of cirrhosis is done without IV contrast. In Swedish practice, it should be done within 2 months in suspected cirrhosis.[notes 2]

In abnormal liver function tests without pain, a combined ultrasonography of the biliary tract and liver is indicated. In Swedish practice, it should be done within 4 to 8 weeks.[notes 2] If concurrent pain, consider ultrasonography of gallstones.

General screening

A general screening of the liver includes:

Also, in suspected liver disease, it is often indicated to perform a general upper abdominal screening.

Size

Abdominal ultrasonography of the liver, as a sagittal plane through the midclavicular line, with some standard measurements.[1]
Normal craniocaudal dimension of the posterior surface of the right lobe of the liver at the midclavicular line at ages 0 to 7.[2]
  • Basic evaluation: Maximum dimension on a sagittal plane view through the midclavicular line, which is normally up to 18 cm in adults.[1]
  • More comprehensive, also including:
  • Cranio-caudal dimension, which is normally up to 15 cm in adults.[1]
  • Ventro-dorsal dimension (or depth), which is normally up to 13 cm.[1]
  • Relative size of caudate lobe: In the axial plane, the caudate lobe should normally have a cross-section of less than 0.55 of the rest of the liver.[1]
