Specialty area: Emerging Brain Techniques Highlights: 1. QSM quantifies magnetic properties of tissue
نویسنده
چکیده
Phase and magnetic susceptibility maps derived from gradient-echo MRI provides a unique contrast among various cortical and sub-cortical gray and white matter tissues (1-9). The excellent tissue contrast has been largely attributed to the sensitivity of magnetic susceptibility to the spatial variations of molecular or cellular components, especially iron and myelin that are of different magnetic properties compared to bulk water (3,8,10-15). The objectives of the lecture are to understand the underlying concepts of QSM; to explain the basic acquisition and processing protocols of QSM; to recognize the benefits and pitfalls of QSM in CNS applications.

Comparison of Two Quantitative Susceptibility Mapping Measurement Methods Used For Anatomical Localization of the Iron-Incorporated Deep Brain Nuclei
Introduction Quantitative susceptibility mapping (QSM) is a new contrast mechanism in magnetic resonance imaging (MRI). The images produced by the QSM enable researchers and clinicians to easily localize specific structures of the brain, such as deep brain nuclei. These nuclei are targets in many clinical applications and therefore their easy localization is a must. In this study, we aimed to i...
متن کاملOn the role of physiological fluctuations in quantitative gradient echo MRI: implications for GEPCI, QSM, and SWI.
PURPOSE Physiological fluctuations in biological tissues adversely affect MR images if present during signal acquisition. This problem is especially important for quantitative MRI. The goal of the studies reported in this study was to reduce the contributions of physiological fluctuations in quantitative MRI based on T2* tissue relaxation properties. Specifically, in this study we deal with GEP...
متن کاملSusceptibility-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 ...

Quantitative susceptibility mapping (QSM) has only recently entered the ever increasing armamentarium of magnetic resonance imaging. It represent a novel quantitative contrast of an intrinsic physical tissue property that may be regarded as one of the most fundamental properties in the context of magnetic resonance imaging because it reflects the reaction of the tissue to the static main magnet...
متن کاملMRI estimates of brain iron concentration in normal aging using quantitative susceptibility mapping
Quantifying tissue iron concentration in vivo is instrumental for understanding the role of iron in physiology and in neurological diseases associated with abnormal iron distribution. Herein, we use recently-developed Quantitative Susceptibility Mapping (QSM) methodology to estimate the tissue magnetic susceptibility based on MRI signal phase. To investigate the effect of different regularizati...
