Overview
Ultrasound may be helpful in the diagnosis of non-alcoholic fatty liver disease. Ultrasound is often considered as the first line of imaging choice to diagnose non-alcoholic fatty liver disease. Increased echogenicity and coarsened echotexture of the liver is the most prominent and diagnostic finding on an ultrasound in patients diagnosed non-alcoholic fatty liver disease.
Ultrasound
- Ultrasound is considered as the first line of imaging choice for NAFLD patients [1][2]
- Ultrasound have senstivity of 60-100 and 80-100 % of positive predictive value.
- Findings on an ultrasound suggestive of non-alcoholic fatty liver disease include:
- Moderate to high amount of fatty infiltration of liver which is reflected as increased echogenicity and coarsened echotexture of the liver.
- If steato-hepatitis has progressed to cirrhosis, a nodular liver surface may be present in addition to other fibrotic changes.[3]
- Ultrasound elastography is another kind of ultrasound that can give qualitative progression of the liver fibrosis.
- The only limitation of using an ultrasound is that it cannot differentiate between hepatic fibrosis and steatosis.
