Popis:	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 from MRE images generated using FUS and that using previously reported MRE techniques. The shear wave displacement amplitude at the FUS focus was studied and found to be proportional with both FUS ultrasonic pulse intensity and the FUS modulation pulse period over the range tested.
