ABSTRACT

Elastography is an imaging technique where elasticity of tissue is determined non-invasively to differentiate between normal and diseased tissue. Among different types of elastography like Ultrasound Elastography and Magnetic Resonance Elastography, Ultrasound Elastography is widely use technique. Abnormal tissue deform to lesser extent than normal tissue after compression. Images are taken before and after the compression. Elastogram is one where different shades of colours are use to represent the tissue elasticity. Elastography is used from mid- 1990s. It is better alternative for the biopsy which is an invasive procedure. Present article covers an overview of the different forms and clinical applications of Elastography.

Keywords: Elastography, elasticity, compression, displacement.
