Dynamic 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 کاملCross-Validation of Magnetic Resonance Elastography and Ultrasound-based Transient Elastography in Phantom Materials
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 کاملObservation of nonlinear shear wave propagation using magnetic resonance elastography.
MR elastography (MRE) is an MRI modality that is increasingly being used to image tissue elasticity throughout the body. One MRE technique that has received a great deal of attention is based on visualizing shear waves, which reveal stiffness by virtue of their local wavelength. However, the shape of propagating shear waves can also provide valuable information about the nonlinear stress-strain...
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...
