Alternative definition : CDISC: A noninvasive technique that is used to measure organ or tissue stiffness.
An ultrasound wave is passed into the organ or tissue from a small transducer on the
end of an ultrasound probe which measures the velocity of the shear wave (in meters
per second) as this wave passes through the organ or tissue. The shear wave velocity
can then be converted into organ or tissue stiffness. This technique may be used as
an alternative to organ or tissue biopsy.;
