We developed a new technique for dynamic MR elastography (MRE) using a MR magnitude image. A general MRE uses a MR phase image as a wave image. Proposed technique was used a MR magnitude image instead of MR phase image as a wave image by using a special vibration. Proposed technique (special vibration MRE) performance was comparable to that of a continuous vibration MRE. Since special vibration MRE need an only few second vibration, it could dramatically eliminated the patients' vibration-related discomfort.
