Rapid multi-orientation quantitative susceptibility mapping
Three-dimensional gradient echo (GRE) is the main workhorse sequence used for susceptibility weighted imaging (SWI), quantitative susceptibility mapping (QSM), and susceptibility tensor imaging (STI). Achieving optimal phase signal-to-noise ratio requires late echo times, thus necessitating a long repetition time (TR). Combined with the large encoding burden of whole-brain coverage with high re...
متن کاملRapid Multi-Orientation Susceptibility Mapping with Wave-CAIPI
Target Audience: Physicians and scientists interested in rapid Quantitative Susceptibility Mapping (QSM) and Susceptibility Tensor Imaging (STI). Purpose: QSM estimates the magnetic susceptibility that is related to subtle changes in the magnetic field through the dipole convolution , where and represent discrete Fourier transform and the dipole kernel. Inversion of this ill-posed system can be...
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 کاملFunctional quantitative susceptibility mapping (fQSM)
Blood oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI) is a powerful technique, typically based on the statistical analysis of the magnitude component of the complex time-series. Here, we additionally interrogated the phase data of the fMRI time-series and used quantitative susceptibility mapping (QSM) in order to investigate the potential of functional QSM (fQSM)...
