Preferred Term:
elasticity imaging techniques
Definition:
Non-invasive imaging methods based on the mechanical response of an object to a vibrational or impulsive force. It is used for determining the viscoelastic properties of tissue, and thereby differentiating soft from hard inclusions in tissue such as microcalcifications, and some cancer lesions. Most techniques use ultrasound to create the images-eliciting the response with an ultrasonic radiation force and/or recording displacements of the tissue by Doppler ultrasonography.
