Overview
The ultrasound may be used as a screening tool in patients with chronic hepatitis for the early detection of hepatic cirrhosis. HBsAg carriers with cirrhosis should be echographically evaluated every 6 months.
Ultrasound
The following findings may be identified:[1]
- Coarse echogenicity
- Segmental hypertrophy with nodular appearance of the liver
- Portal hypertension:
HBsAg carriers should have regular serial serum alpha-fetoprotein determinations, and ultrasound examinations for those above 40 years of age (with 6 month intervals).[2]
Both these tests are recommended to be repeated regularly, for all HBsAg carriers with cirrhosis.[1]
