Magnetic susceptibility anisotropy of myocardium imaged by cardiovascular magnetic resonance reflects the anisotropy of myocardial filament α-helix polypeptide bonds

Magnetic susceptibility anisotropy of myocardium imaged by cardiovascular magnetic resonance reflects the anisotropy of myocardial filament α-helix polypeptide bonds

BACKGROUND A key component of evaluating myocardial tissue function is the assessment of myofiber organization and structure. Studies suggest that striated muscle fibers are magnetically anisotropic, which, if measurable in the heart, may provide a tool to assess myocardial microstructure and function. METHODS To determine whether this weak anisotropy is observable and spatially quantifiable ...

A review of Anisotropy of Magnetic Susceptibility analysis of Indian dykes: Implications on magma emplacement

The analysis of Anisotropy of Magnetic Susceptibility (AMS) is a powerful and rapid technique to examine the preferred orientations of mineral (magnetic) fabrics and can indicate the nature of a magma transport (vertical or lateral). The relationship between magnetic fabric and geometry of a dyke swarm enables us to understand magma emplacement processes. Depending on the mutual relationship of...

Magnetic Resonance Spectroscopy for the Determination of Magnetic Anisotropy

Magnetic Susceptibility Anisotropy of Central Nervous System

INTRODUCTION : Magnetic susceptibility difference between brain gray and white matter results in strong phase contrast between these two types of tissues at high magnetic field strength (1, 2). Here, we report, for the first time, a surprising observation of tissue-level magnetic susceptibility anisotropy in the central nervous system (CNS) using a mouse model. Specifically, we propose a method...
