What is it indicated for?
MR Elastography is a software and hardware option intended for use on Achieva and Ingenia 1.5T and 3.OT MR Systems for producing images representing tissue stiffness of the abdomen area such as liver and muscle. MR Elastography applies an MR acquisition sequence synchronized with an external source of vibration to produce images representing tissue stiffness (in kiloPascals, kPa). The stiffness image production technique also creates an overlay representing thie reliability of the stiffness image production algorithm.
Indications for use as stated in the FDA summary.
