Mixed model phase evolution for correction of magnetic field inhomogeneity effects in 3D quantitative gradient echo-based MRI.
PURPOSE In 3D gradient echo magnetic resonance imaging (MRI), strong field gradients B0macro are visually observed at air/tissue interfaces. At low spatial resolution in particular, the respective field gradients lead to an apparent increase in intravoxel dephasing, and subsequently, to signal loss or inaccurate R2* estimates. If the strong field gradients are measured, their influence can be r...
متن کاملP 24: Evaluation of the Voxel Based Morphometry in Quantitative Analysis of Brain MRI Images
Introduction: Voxel based morphometry is a type of statistical parametric mapping that can be used to investigate the effect of diseases such as epilepsy, Alzheimer's disease and Parkinson's disease or other agent such as skills on brain structure (white matter, gray matter and cerebrospinal fluid). The aim of this study is evaluate the effectiveness of this method in detection of differen...
متن کاملSOM for intensity inhomogeneity correction in MRI
Given an appropriate imaging resolution, a common Magnetic Resonance Imaging (MRI) model assumes that object under study is composed of piecewise constant materials, so that MRI produces piecewise constant images. The intensity inhomogeneity (IIH) is modeled by a multiplicative inhomogeneity field. It is due to the spatial inhomogeneity in the excitatory Radio Frequency (RF) signal and other ef...
متن کاملSWI-based method for emphasizing susceptivity changes on liver T2* multi-echo gradient-echo MRI
Introduction It is well known that the susceptibility difference between tissues, such as venous blood and surrounding tissue, causes a different bulk magnetization that can be observed both in magnitude and phase images: as a signal amplitude loss due to a reduced T2*, and as a local frequency variation of the protons inside the vessel that results in a phase angle Φ of the venous blood signal...
