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 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 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 کاملQuantitative Susceptibility Mapping In Vivo in the Rat Brain
INTRODUCTION Molecular and cellular imaging is seeing a growing interest, but their applicability to MRI relies on the ability for the label to be specific, sensitive enough and quantifiable via adapted imaging methodologies. Superparamagnetic iron oxides (SPIO) are good candidates as they can be functionalized or used to label cells (1). More recently, it was shown that they could be directly ...
متن کاملSusceptibility weighted imaging (SWI).
Susceptibility differences between tissues can be utilized as a new type of contrast in MRI that is different from spin density, T1-, or T2-weighted imaging. Signals from substances with different magnetic susceptibilities compared to their neighboring tissue will become out of phase with these tissues at sufficiently long echo times (TEs). Thus, phase imaging offers a means of enhancing contra...
