Ultra-high Field MRI of the Kidney

, 2023
The current literature on ultra-high field MRI of the kidneys indicates that kidney imaging can clearly benefit from a significant increase in field strength for anatomic, functional, and metabolic studies. However, many advantages are accompanied by numerous technical difficulties, including inhomogeneity of the static (B0) and radiofrequency (RF ...

The impact of ultra-high field MRI on cognitive and computational neuroimaging [PDF]

NeuroImage, 2018
The ability to measure functional brain responses non-invasively with ultra high field MRI (7 T and above) represents a unique opportunity in advancing our understanding of the human brain. Compared to lower fields (3 T and below), ultra high field MRI has an increased sensitivity, which can be used to acquire functional images with greater spatial ...

Multinuclear Magnetic Resonance Spectroscopy at Ultra-High-Field: Assessing Human Cerebral Metabolism in Healthy and Diseased States

Metabolites, 2023
The brain is a highly energetic organ. Although the brain can consume metabolic substrates, such as lactate, glycogen, and ketone bodies, the energy metabolism in a healthy adult brain mainly relies on glucose provided via blood.

Evaluation of High Intracranial Plaque Prevalence in Type 2 Diabetes Using Vessel Wall Imaging on 7 T Magnetic Resonance Imaging

Brain Sciences, 2023
Background: While type 2 diabetes (T2D) is a major risk for ischemic stroke, the associated vessel wall characteristics remain essentially unknown. This study aimed to clarify intracranial vascular changes on three-dimensional vessel wall imaging (3D-VWI)

Imaging perivascular space structure and function using brain MRI

NeuroImage, 2022
In this article, we provide an overview of current neuroimaging methods for studying perivascular spaces (PVS) in humans using brain MRI. In recent years, an increasing number of studies highlighted the role of PVS in cerebrospinal/interstial fluid ...

Magnetisation transfer effects at ultra high field MRI [PDF]

, 2017
Increased signal to noise ratio in ultra high field Magnetic Resonance Imaging (MRI) has allowed the development of quantitative imaging techniques and new contrast mechanisms, such as Chemical Exchange Saturation Transfer (CEST) to be probed. \ud The development of CEST contrast imaging has involved overcoming a number of technical challenges ...
