talk in 500-520 words about (shear wave elastography)

Answer 1

share wave elastography is allows quantification of mechanical and elastic tissue properties. it has a promising role in determining the severity of disease and treatment follow-up of various musculoskeletal tissues including muscles, ligaments, tendons, nerves. it is a rapidly evolving US imaging technique.

Shear-wave images are coregistered automatically with standard B-mode images to provide quantitative color elastograms with anatomic specificity. shear waves propagate is faster through , long axis of tendon and muscle and stiffer contracted tissue. In breast disease which can obtain quantitative elasticity values. share wave elastography is considered to be more objective, quantitative, and reproducible than compression sonoelastography with increasing applications to the musculoskeletal system.

Shear-wave images  uses an acoustic radiation force pulse sequence to generate shear waves, which propagate perpendicular to the ultrasound beam, causing transient displacements. we believe that shear-wave elastography may help in predicting impending tendon failure, and in that way may help the clinician in making decisions in early initiation of treatment. In addition to several ongoing research projects, shear-wave elastography elastography is frequently used in the authors’ institutions as an adjunct to conventional US techniques in the routine clinical evaluation of tissue elasticity of various traumatic and pathologic conditions of the musculoskeletal system. we believe that shear-wave elastography may help in predicting impending tendon failure. that way may help the clinician in making decisions in early initiation of treatment.

Present shear-wave elastography was of the greatest help in the evaluation of tendons, followed by muscles and peripheral nerves. We explore the sonoelastography has been progressively used as a tool to help evaluate soft-tissue elasticity and add to information obtained with conventional gray-scale and Doppler ultrasonographic techniques.  Shear-wave images uses an acoustic radiation force pulse sequence to generate shear waves, which propagate perpendicular to the ultrasound beam, causing transient displacements.
