HYPOTHESIS: The investigators hypothesize that sonoelastography (SE) will provide accurate quantitative measurements that can be used to stage liver fibrosis in patients with chronic liver disease.
- To measure liver stiffness with sonoelastography in adults with suspect diffuse liver disease who will undergo non-focal liver biopsy as part of their routine clinical care
- To assess the sensitivity and specificity of sonoelastography for the detection and staging of liver fibrosis
- To evaluate the effect of steatosis and inflammation on the estimation of liver fibrosis using sonoelastography

Experimental: Shear Wave Sonoelastography for Fibrosis Assessment
Shear Wave sonoelastography (SWE) was performed in patients who were scheduled for a non-focal liver biopsy.
Device: Shear Wave Sonoelastography
Shear Wave sonoelastography (SWE) as an ultrasound technique to measure liver fibrosis was performed on patients scheduled for non-focal liver biopsy. Results were compared with pathological score from liver biopsy.

- Liver Elasticity Value Measured Using Sonoelastography (SE) [ Time Frame: Day 1 ]Liver elasticity/stiffness was assessed via SE and compared against results of liver biopsy as read by a single pathologist using the Meta-analysis of Histological Data in Viral Hepatitis (METAVIR) 5-point scale (F [Fibrosis]0=no fibrosis, F1=portal fibrosis without septa, F2=portal fibrosis with few septa, F3=numerous septa without cirrhosis, and F4=cirrhosis). Using SE, fibrosis is measured in kilopascals (kPa) with normal values equaling approximately 5.5 kPa (normal liver stiffness ranges between 3.3-7.8 kPa). Significant Fibrosis (F3): = or > 7.6 kPa, Cirrhosis (F4): = or > 9.0- 26 kPa. A higher number corresponds to an increase in stiffness and hepatic fibrosis.
