Echo-Planar Susceptibility Mapping
Purpose: Quantitative susceptibility mapping (QSM) is a valuable new approach for subcortical brain iron mapping [1,2]. However, acquisition times are typically on the order of 5-10 minutes, which is acceptable in dedicated studies but limits wider use in the clinic for standard brain exams due to the considerable time penalty. The aim is to develop and test an extremely rapid means (under 10 s...
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)...
متن کاملHematoma volume measurement in gradient echo MRI using quantitative susceptibility mapping.
BACKGROUND AND PURPOSE A novel quantitative susceptibility mapping (QSM) processing technology has been developed to map tissue susceptibility property without blooming artifacts. We hypothesize that hematoma volume measurement on QSM is independent of imaging parameters, eliminating its echo time dependence on gradient echo MRI. METHODS Gradient echo MRI of 16 patients with intracerebral hem...
متن کاملSimultaneous Quantitative MRI Mapping of T1, T2* and Magnetic Susceptibility with Multi-Echo MP2RAGE
The knowledge of relaxation times is essential for understanding the biophysical mechanisms underlying contrast in magnetic resonance imaging. Quantitative experiments, while offering major advantages in terms of reproducibility, may benefit from simultaneous acquisitions. In this work, we demonstrate the possibility of simultaneously recording relaxation-time and susceptibility maps with a pro...
