Editorial: Quantitative Susceptibility Mapping in Neurodegeneration
The purpose of this study was to evaluate the effect of resolution on iron content using quantitative susceptibility mapping (QSM); to verify the consistency of QSM across field strengths and manufacturers in evaluating the iron content of deep gray matter…
The Future of Quantitative Susceptibility Mapping (QSM) in Clinical Applications
The use of Quantitative Susceptibility Mapping (QSM) is often viewed as incompatible with current standard radiology workflows. Some radiologists or departments may be unaware of its existence or purpose. Despite the skepticism surrounding its viability in a clinical setting, QSM shows great potential in a wide range of clinical applications, particularly for biomarker detection and… “The Future of Quantitative Susceptibility Mapping (QSM) in Clinical Applications”
Revealing vascular abnormalities and measuring small vessel density in multiple sclerosis lesions using USPIO
In this study, an ultra-small superparamagnetic iron oxide (USPIO) contrast agent, Ferumoxytol, was administered to induce an increase in susceptibility for both arteries and veins to help better reveal the cerebral microvasculature. The purpose of this work was to examine…
Quantifying Tissue Properties of the Optic Radiations Using Strategically Acquired Gradient Echo Imaging and Enhancing the Contrast Using Diamagnetic Susceptibility Weighted Imaging
Visualization of the optic radiations is of clinical importance for diagnosing many diseases and depicting their anatomic structures for neurosurgical interventions. In this study, we quantify proton density, T1, T2*, and susceptibility of the optic radiation fiber bundles in a…
Quantitative MRI using STrategically Acquired Gradient Echo (STAGE): optimization for 1.5 T scanners and T1 relaxation map validation
The strategically acquired gradient echo (STAGE) protocol, developed for 3T scanners, allows one to derive quantitative maps such as T1, T2*, proton density, and quantitative susceptibility mapping in about 5 min. Our aim was to adapt the STAGE sequences for…
Iron Content in Deep Gray Matter as a Function of Age Using Quantitative Susceptibility Mapping: A Multicenter Study
The purpose of this study was to evaluate the effect of resolution on iron content using quantitative susceptibility mapping (QSM); to verify the consistency of QSM across field strengths and manufacturers in evaluating the iron content of deep gray matter…
Imaging iron and neuromelanin simultaneously using a single 3D gradient echo magnetization transfer sequence: Combining neuromelanin, iron and the nigrosome-1 sign as complementary imaging biomarkers in early stage Parkinson’s disease
Diagnosing early stage Parkinson’s disease (PD) is still a clinical challenge. Our goal in this study was to extract the NM complex volume, iron content and volume representing the entire SN, and the N1 sign as potential complementary imaging biomarkers…
Imaging of the Spinal Cord in Multiple Sclerosis: Past, Present, Future
