Magnetic Resonance Elastography in Patients With Abdominal Aortic Aneurysms

This device is used to generate vibrations at the area of interest. The device has an active driver, a loud speaker sitting outside the scanner area, and a passive driver, which is shaped like a silicone paddle, which is secured with velcro straps to the area being imaged. Sound waves from the active driver travel through a tube attached to the passive driver and generate vibrations, images of which are captured by the MR scanner.
