When an area of the brain is in use blood flow to that region also increases. MRI does not involve X-rays or the use of ionizing radiation which distinguishes it.
Basics Of Nmr
Emphasis is on the quantitative measurement of molecular parameters and transformations.
. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. Optical and magnetic resonance spectroscopy are used to investigate the structural dynamic and quantum mechanical properties of some basic chemical systems. Magnetic resonance imaging MRI is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body.
MRI scanners use strong magnetic fields magnetic field gradients and radio waves to generate images of the organs in the body. Nuclear magnetic resonance was discovered simultaneously by two physicists Felix Bloch and Edward Mills Purcell just after the end of the Second World War. This course has an associated fee.
Bloch trained in quantum mechanics and was involved with atomic energy and then radar countermeasures. At the end of the war he returned to his earlier work on the magnetic moment of the neutron. Functional magnetic resonance imaging or functional MRI fMRI measures brain activity by detecting changes associated with blood flow.
