Core Tip

Core Tip: Artifacts are common when using two-dimensional shear wave elastography (2-D SWE) to measure liver stiffness (LS), especially for the novice. We investigated the presence and influence of artifacts in 2-D SWE of liver. Our results showed artifacts were more likely to occur in the bottom-left corner of the elastogram. Artifacts may lead to the overestimation of LS and reduce the repeatability and reliability of LS measurements. For the elastograms with artifacts, we should place the Q-Box away from the artifacts.
