The magnetic resonance signal
has an amplitude that depends on water content and a lifetime that depends on the water environment, namely, cell wall or cell lumen.
Among the topics are magnetic resonance imaging (MRI) scanners, basic principles of magnetic resonance signal
generation and image formation, MRI contrast mechanisms and acquisition techniques, the origins and properties of blood-oxygen-level-dependent (BOLD) functional MRI (fMRI), basic and advanced approaches to statistical analysis, advanced fMRI methods, and combining fMRI with other techniques.
In the magnetic resonance signal
, this magnetic field will induce a phase shift, [phi], of
Effects of brain membranes on 1H nuclear magnetic resonance signal
intensity of ethanol in vitro.
Magnetic resonance signal
characteristics of lipomas are quite specific; lipomas have high signal intensity on T1 and T2 weighted images and their signal are suppressed by fat suppression sequence and by this way cardiac MRI become diagnostic in this case.
The technology operates under the principle that a magnetic resonance signal
can be detected from explosives without applying a large external magnetic field.
The purpose of selection techniques is to precisely measure assigned voxels by reading the magnetic resonance signal
in the selected voxel only.
In the case of wood logs, measurements of magnetic resonance signal
in the sapwood are therefore possible without first removing the bark.
Even the founders of magnetic resonance theory had pondered whether interactions among spins on different molecules could contribute to the magnetic resonance signal
. But they concluded that the magnetic forces between widely separated spins could be ignored.
These researchers have developed a means for recovering useful magnetic resonance signals
from materials within a nonuniform magnetic field.
The fifth core, the Electron Spin Resonance (ESR) Core, uses magnetic resonance signals
to detect and measure the presence of free radicals in tissues.
