Abstract

2 D shear wave elastography (2D-SWE) is the latest evolution of elastography techniques and allows real-time quantitative assessment of the medium stiffness. The aim of this review is to identify, describe, explain and illustrate some technical restrictions and artifacts in 2D-SWE. Encountered artifacts and technical restrictions may be categorized according to acquisition technique, medium, or operator:Clear knowledge of the underlying physical basis is necessary in 2D-SWE because radiologists have to deal with technical restrictions and a wide range of artifacts. Proper use of 2D-SWE ensures the reliability and reproducibility of the technique.
