Can liver cirrhosis be detected by an ultrasound B-scan?
Liver cirrhosis can be diagnosed with an ultrasound. In the early stages of cirrhosis, there are no specific changes in the sonographic pattern visible on ultrasound. Typically, cirrhosis manifests as a decrease in liver volume, with imbalanced proportions of the liver lobes; both the left and right lobes may shrink, with compensatory hypertrophy observed in some cases in the left lobe. The liver capsule appears serrated, and the echoes from the liver area are coarser and stronger, with uneven distribution. It's possible to observe nodules with low or high echoes. The liver vessels vary in thickness, the hepatic veins may narrow, and the portal vein can widen. An enlarged portal vein can lead to symptoms like splenomegaly and ascites.
