FERRANDO, Nicolás et al. Association of liver fibrosis using 2D shear wave elastography and APRI score. Rev. Urug. Med. Int. [online]. 2023, vol.8, n.3, pp.48-58.  Epub Dec 01, 2023. ISSN 2393-6797.


Liver diseases are a prevalent problem worldwide. To date, liver biopsy has been the gold standard for assessing the degree of fibrosis; however, with the advent of new non-invasive, cost-effective methods for the healthcare system, we are resorting to it less and less. Shear wave elastography with biplanar imaging was recently introduced in our setting, which implies a learning curve for technicians.


To assess the association of the degrees of liver fibrosis determined by shear wave elastography with biplanar imaging (2D-SWE) and the APRI score in patients with liver disease treated in the hepatology service of the Pasteur Hospital.


Patients with liver disease of any etiology, attended between 01/10/21 and 08/31/22, over 15 years of age, of both sexes and who have been evaluated with shear wave elastography with biplanar image were included. (2D-SWE) and blood analysis performed by the medical team of the aforementioned service in the last 6 months.


158 patients were included. A higher prevalence of liver disease was found in women, with a predominance of the etiology of nonalcoholic fatty liver disease (NAFLD) and hepatitis C virus (HCV) infection. A positive association was evident between elastography (2D-SWE) and the APRI score for the diagnosis or exclusion of advanced liver disease, with no statistically significant difference between the two hepatologists.


There is an association between SWE elastography and the APRI score for the diagnosis of advanced liver disease in the general population and by etiology.

Keywords : Advanced liver disease; APRI score; shear wave elastography with biplanar imaging; 2D-SWE; METAVIR scale.
