Scatter-based magnetic resonance elastography.
Elasticity is a sensitive measure of the microstructural constitution of soft biological tissues and increasingly used in diagnostic imaging. Magnetic resonance elastography (MRE) uniquely allows in vivo measurement of the shear elasticity of brain tissue. However, the spatial resolution of MRE is inherently limited as the transformation of shear wave patterns into elasticity maps requires the ...

Fig. 1 (a) MRE wave image and Elastogram (b) UTE spatio-temporal strain map (c) Bland-Altman plot MRE: FOV=14cm,Matrix=256X64,TR/TE=50/26.5ms, flip angle=30 ̊, thickness=10cm, BW=±16kHz, continues vibration=60Hz, average stiffness of ROI drawn on the elastogram was measured as the stiffness of the phantom. UTE: center frequency of transducer=3.5 MHz, transient vibration=20ms (1 cycle of 50 Hz si...
متن کاملQuantitative 3D magnetic resonance elastography: Comparison with dynamic mechanical analysis
PURPOSE Magnetic resonance elastography (MRE) is a rapidly growing noninvasive imaging technique for measuring tissue mechanical properties in vivo. Previous studies have compared two-dimensional MRE measurements with material properties from dynamic mechanical analysis (DMA) devices that were limited in frequency range. Advanced DMA technology now allows broad frequency range testing, and thre...
متن کاملDynamic Magnetic Resonance Elastography
There is strong precedent in clinical medicine for the concept that tissue viscoelastic properties, assessed by palpation, are markedly affected by a variety of disease processes. Student physicians learn that the presence of a hard mass in the thyroid, breast, or prostate is suspicious for malignancy. Indeed, many tumors of these structures are still first detected by touch. It is not uncommon...
متن کاملOverhauser-enhanced magnetic resonance elastography.
Magnetic resonance elastography (MRE) is a powerful technique to assess the mechanical properties of living tissue. However, it suffers from reduced sensitivity in regions with short T2 and T2 * such as in tissue with high concentrations of paramagnetic iron, or in regions surrounding implanted devices. In this work, we exploit the longer T2 * attainable at ultra-low magnetic fields in combinat...
