Abstract:
Magnetic resonance acoustography images are acquired in real time using a one-dimensional magnetic resonance elastography (MRE) pulse sequence in which a column of tissue is excited. A spin-echo MRE pulse sequence and a gradient-echo MRE pulse sequence are described which employ a broadband motion sensitizing gradient that enables an asynchronous transducer to be used to produce the oscillatory stress in the subject tissues.
