Abstract
This study has shown that magnetic resonance elastography (MRE) can detect shear waves excited by focused ultrasound (FUS) in both gel phantoms and ex vivo muscle. Good agreement was shown between the shear modulus measured f rom MRE images generated using FUS and that using previously reported MRE t echniques. The shear wave displacement amplitude at the FUS focus was studi ed and found to be proportional with both FUS ultrasonic pulse intensity an d the FUS modulation pulse period over the range tested.
