Body Mass Index and Liver Stiffness Affect Accuracy of Ultrasonography in Detecting Steatosis in Patients With Chronic Hepatitis C Virus Genotype 1 Infection

Ultrasonography detects steatosis with low levels of accuracy in patients with chronic hepatitis C virus genotype 1 infection; it has low NPVs for amounts of steatosis of 5% or more and low PPVs for livers with moderate-severe amounts. Higher body mass indexes and liver stiffness measurements are associated with false-negative results in steatosis detection by ultrasonography.
