• 304 Simple method of magnetic resonance elastography

抄録

In recent years, an elastography has come to be performed using ultrasound imaging (US) of magnetic resonamce imaging (MRI). Existing MR elastography (MRE) pulse sequence was build the several bipolar magnetic field gradients (motion sensitizing gradient: MSG) into a conventional MR pulse sequence, and was synchronizes the vibration to imaging object and MSG. However, built-in MSG extends echo time (TE) and extension of TE dose the debasement of signal to noise ratio (SNR), and the influence of magnetic susceptibility. The purpose of this study was we developed a high-speed MRE pulse sequence that does not need built-in MSG (no extension of TE), and was to examine the potential of this method by phantom experiment.
