Liver stiffness by shear wave elastography is influenced by meal and meal-related haemodynamic modifications

Purpose: To evaluate the effect of meal and meal-related haemodynamic variations on LS measurement by Shear Wave Elastography, given the emerging role of this technique in the non-invasive evaluation of liver fibrosis. Material and methods: 10 healthy volunteers were enrolled in the study. LS, echo color Doppler analysis of portal vein and hepatic artery, as well as liver and spleen dimensions were evaluated before a meal (T0) and 30' (T30), 60'(T60) and 120' (T120) postprandially. Results: LS values increased 30' postprandially and decareased from 60' postprandially, returning to baseline values after 2 hours (…
