    ABSTRACT: To investigate the potential value of magnetic resonance elastography (MRE) in evaluating the consistency of brain tumors. Six patients with known solid brain tumor underwent brain MRE studies. Consistency of brain tumors was evaluated at surgery. Correspondence of MRE evaluation with operative result was studied. The elasticity of tumors in six patients evaluated by MRE agreed with the tumor consistency given by the operative results. MRE could be used as an imaging technique for noninvasive assessment of the consistency of brain tumor in vivo.

    ABSTRACT: To study the application of magnetic resonance elastography (MRE) in the human brain. An external force actuator was developed, which produced propagating shear waves in brain tissue. A modified phase-contrast gradient-echo sequence was developed. The propagating shear waves within the brain were directly imaged. The wave images were processed to obtain the elasticity image. Shear waves at 100 Hz, 150 Hz, and 200 Hz were applied. The propagating shear waves in the brain were visualized on wave images. The elasticity image revealed the difference in tissue elasticity between gray and white matter of the brain. MRE could be an imaging technique for assessing the elasticity of brain tissue.
