The greater the Young’s modulus value 硕士研究生，医师。首 is, the greater the hardness is. Shear wave elastography technology has advantages of real time, 都医科大学附属北京友 dynamic, noninvasion and good repeatability. Nowadays this technique has been widely applied in the evaluation and diagnosis of mammary gland, thyroid gland, liver disease and other 谊医院超声科，从事超 diseases. This paper reviews the progress of shear wave elastography in the clinical application. 声诊断工作。 [Key words] Ultrasound; Shear wave; Elastography; Young’s modulus [First-author’s address] Department of Ultrasound, Beijing Friendship Hospital, Capital Medical University, Beijing 100050, China.
