Acoustoelastography
Acoustoelastography (pronounced: a-cous-toe-elas-to-graphy) is a medical imaging technique used to measure the elastic properties of biological tissues. It is a form of Elastography that uses Ultrasound waves to create images of the stiffness or elasticity of tissues.
Etymology
The term "Acoustoelastography" is derived from three Greek words: "akoustos" meaning "heard", "elastos" meaning "ductile, flexible", and "graphia" meaning "description".
Procedure
In Acoustoelastography, an ultrasound transducer is used to send sound waves into the body. The waves travel through the tissues and are reflected back to the transducer. The speed and intensity of the reflected waves are affected by the stiffness of the tissues they pass through. By analyzing these changes, a computer can create an image that shows the elasticity of the tissues. This can help doctors diagnose a variety of conditions, such as Liver Fibrosis or Breast Cancer.
