Recent studies have shown that real-time, twodimensionalshear-wave elastography (2D-SWE) canmonitor liver fibrosis by measuring tissue elasticity (i.e.,elastic modulus). Two clinical studies of 2D-SWE in theliver have shown that there are several practical issues thatcan compromise quantitation of liver tissue elasticity. Bothgeneral ultrasound (US) limitations and limitations in the2D-SWE method itself resulted in significant variability inestimated liver elasticity. The most common US limitationswere: poor acoustic window, limited penetration, and rib/lung shadows. The most common 2D-SWE limitationswere: reverberations under the liver capsule, respiratory/cardiac motion, and vessel pulsation/loss of SWEsignal. Based on these studies, scan protocols have beenoptimized to minimize the influence of these limitations onliver elasticity quantification. These refined protocolsshould move non-invasive SWE closer to becoming thepreferred tool to diagnose and manage many chronic diseasesof the liver.
