Susceptibility-weighted imaging and quantitative susceptibility mapping in the brain.
Susceptibility-weighted imaging (SWI) is a magnetic resonance imaging (MRI) technique that enhances image contrast by using the susceptibility differences between tissues. It is created by combining both magnitude and phase in the gradient echo data. SWI is sensitive to both paramagnetic and diamagnetic substances which generate different phase shift in MRI data. SWI images can be displayed as ...
متن کاملDiagnosis of patients with Parkinson's disease using quantitative susceptibility mapping
Introduction: Parkinson'sdisease isassociated withirondeposition in the brain. The T2-weighted imaging, T2* mapping, R2 mapping and Quantitative Susceptibility Mapping (QSM) are three common methods to evaluating the iron deposition in brain. Among three methods the QSM is more sensitive than others. Few studies have been used QSM for evaluating the iron deposition in the basa...

متن کاملSusceptibility Weighted Imaging and Susceptibility Mapping (SWIM): A New Means to Visualize Veins and Quantify Susceptibility
Introduction: Susceptibility weighted imaging (SWI) has been used for some time as a means to enhance venous vessels using high pass filtered phase images [1,2]. However, efficacy of SWI processing relies especially on an asymmetric voxel aspect ratio [3] and to a slight extent on the relative orientation of the head and the main magnetic field. Therefore, when SWI is collected as high resoluti...
متن کاملDiminished visibility of cerebral venous vasculature in multiple sclerosis by susceptibility-weighted imaging at 3.0 Tesla.
Multiple sclerosis (MS) is a disease of the central nervous system characterized by widespread demyelination, axonal loss and gliosis, and neurodegeneration; susceptibility-weighted imaging (SWI), through the use of phase information to enhance local susceptibility or T2* contrast, is a relatively new and simple MRI application that can directly image cerebral veins by exploiting venous blood o...
