High Resolution Quantitative Susceptibility Mapping at 9.4T
INTRODUCTION Susceptibility weighted imaging at ultrahigh magnetic fields (B0≥7T) has become a new forefront of research, triggered by the anticipated increase in signal-to-noise ratio (SNR), higher spatial resolution, and improved contrast mechanisms. Employing these advantages superb anatomical contrast has already been demonstrated for both magnitude [1,2] and phase images [2-4]. These phase...
متن کاملNeuromelanin-containing, Catecholaminergic Neurons in the Human Brain: Ontogenetic Aspects, Development and Aging
The present review compiles data on the development and aging of neuromelanin (NM)-containing neurons in the central nervous system. Neuromelanin is brownish-to-black pigment that accumulates in the catecholaminergic (noradrenergic and dopaminergic) neurons and is a reliable natural marker that delineates the A1-A14 catecholaminergic groups of Dahlstrom and Fuxe in the human brain. The pigmenta...
متن کاملQuantitative T1, T2, and T2* Mapping and Semi-Quantitative Neuromelanin-Sensitive Magnetic Resonance Imaging of the Human Midbrain
PURPOSE Neuromelanin is a dark pigment granule present within certain catecholamine neurons of the human brain. Here, we aimed to clarify the relationship between contrast of neuromelanin-sensitive magnetic resonance imaging (MRI) and MR relaxation times using T1, T2, and T2* mapping of the lower midbrain. METHODS The subjects were 14 healthy volunteers (11 men and 3 women, mean age 29.9 ± 6....
متن کاملHigh resolution soil moisture mapping
Soil moisture information is of critical importance to real-world applications such as agriculture, water resource management, flood, fire and landslide prediction, mobility, soil hydraulic parameter estimation etc. Many of these applications require soil moisture information at high resolution. While this may be estimated from land surface models, the predictions are often poor due to inadequa...
متن کاملHigh Resolution Quantitative Lorentz Microscopy
The advent of aberration corrected transmission electron microscopy has led to considerable improvements in the field of high resolution electron microscopy imaging. In this paper we show how these developments are applied to imaging of magnetic structure in field free or low field conditions. Whilst the capability of increased spatial resolution is demonstrated on magnetic layers with a width ...
