Study of Shear Wave Displacement Change Measured by 1D MRE During Focused Ultrasound Treatment: Preliminary Study

摘要

A new method is evaluated for using 1D MR elastography to monitor focused ultrasound surgery (FUS) treatment in real time. A MRI compatible ultrasound system was used and 29 pieces of ex vivo porcine tissue and 2 nude mice breast tumor xenoplant were evaluated for the change of shear wave displacement measured at the focus of pulsed ultrasound. This study shows the potential of 1D MR elastography to be used for FUS treatment monitoring.
