E imaging, also named shear wave elastography (SWE) is a real time elastography technology of two-dimensional emerging in recent years. It is not only fundamentally different from the static elastography technique, but also different from transient elastography and acoustic radiation force impulse. A new technology progress has occurred in SWE. In this paper, the related principle of elastography and several elastography technologies in clinical application were introduced, and the methods of achieving rapid, real-time, and extensive testing of SWE were explored. Meanwhile, emerging and detecting methods of SWE, for example, dynamic coherence enhancement technique based on “March Wave” and ultra high frequency imaging technology for one transmitting-receiving were renumbered. Moreover, this paper reviewed the technology researches and clinical applications of SWE, and the future development of SWE was discussed in the end.
