Intensity speckle MR elastography

Introduction: Magnetic resonance elastography (MRE) allows the measurement of the mechanical properties of living tissue by combining shear waves and motion sensitive MRI [1]. In classical MRE, shear wave images are evaluated using an appropriate wave inversion technique for calculating an estimate of the spatial distribution of the shear modulus within the region of interest [2]. Problem: Wave...

Apparent CBF decrease with normal aging due to partial volume effects: MR-based partial volume correction on CBF SPECT.

Several studies using single photon emission tomography (SPECT) have shown changes in cerebral blood flow (CBF) with age, which were associated with partial volume effects by some authors. Some studies have also demonstrated gender-related differences in CBF. The present study aimed to examine age and gender effects on CBF SPECT images obtained using the 99mTc-ethyl cysteinate dimer and a SPECT...

MR Elastography of Peritoneal Tumor

Background: MRE is a phase contrast MRI technique that evaluates the stiffness of tissues by directly visualizing and measuring propagated mechanical shear waves in tissues. MRE generates quantitative measurements and colorized spatial maps of shear wave displacement. The initial wave images are processed to generate an elastogram, which displays the quantitative values of the shear modulus of ...

Wavelet-based partial volume effect correction for simultaneous MR/PET of the carotid arteries

Translational and Molecular Imaging Institute, Icahn School of Medicine at Mount Sinai, NY, NY, USA Simultaneous MR/PET scanners allow for the exploration and development of novel PVE correction techniques without the challenges of coregistration of MR and PET. The development of a wavelet-based PVE correction method, to improve PET quantification, has proven successful in brain PET. We report ...

Effect of Intravenous Gadolinium on Estimation of Liver Stiffness with Mr Elastography

Methods: Liver MRI and MRE were performed in 32 subjects. The indications for liver MRE were suspected fibrosis/cirrhosis (n=24) and liver tumour (n=8). All MRI studies were performed on a single 1.5 Tesla clinical MR scanner (GE, Milwaukee, USA). The MRE was performed before (pre-Gd MRE) and at the end of standard Liver MRI protocol immediately after the 5 minute delayed phase (post-Gd MRE) in...
