Core Tip

Core tip: The gold standard in the diagnosis and staging of liver fibrosis is an invasive liver biopsy. The accuracy of non-invasive tools such as ultrasound shear wave elastography either alone or in combination with the use of the aspartate transaminase platelet ratio index score compared to histology to guide management of liver fibrosis is not known. We addressed this question in a multicenter trial in patients with chronic progressive liver disease in a low to middle income country.
