Elastography New imaging method which provides very high contrast between masses
and host tissue, by estimating the measure of visco-elastic properties of tissues.
Types: Ultrasound Elastography MR Elastography
•Elasticity Imaging looks at mechanical properties -Show relative tissue stiffness or
hardness -Different information than B-mode which shows backscatter information
-Provides further insight into potential pathology •Helps to differentiate hard from
soft lesions. •Differentiates cystic from solid lesions. Advantages of ultrasound in
Elastography: real-time imaging capabilities, very high resolution in motion estimation
(~1mm), simplicity, non-invasiveness, and relative low cost.
