What ACOUSTIC RADIATION FORCE IMPULSE IMAGING means: An imaging technique that shoots short pulses of ultrasound at targeted tissues and then monitors the tissue response in the form of shear waves that can be measured, and displayed as elastography images. These measurements and images can be used to diagnose or monitor the possible presence of diseased or cancerous tissue, based on the measured stiffness properties of tissues such as breast or liver where areas of increased stiffness may indicate the presence of tumors, fibrosis, scar tissue, and other types of disease or damage.
