How does it work?: Magnetic resonance imaging

Telepathy, Using the Force, and Other Paranormal Abilities

“…A very strong magnetic field can also affect atoms and molecules in a living organism's body [19]. This is particularly the case with hydrogen atoms and water molecules, both of which can act as very tiny, weak magnets.…”

Urolithiasis: An Update on Diagnostic Modalities and Treatment Protocols

“…Magnetic resonance imaging uses magnets, radio waves and body's natural magnetic properties for imaging urinary stones, and sometimes requires administration of paramagnetic contrast media for the same [39,40,44,49,50] . It found applicability in visualising pathological changes caused by stones in the urinary tract of paediatric and pregnant patients owing to its superior soft tissue contrast and for it does not carries risk associated with ionizing radiations [38,50] , until high doses of paramagnetic contrast were found to be teratogenic [44] .…”

‘Go with the flow ’: A review of methods and advancements in blood flow imaging

“…Nuclei with an odd number of protons, neutrons or both, have an intrinsic nuclear spin [169,170]. Ordinarily, nuclei spin with their axes randomly aligned.…”

“…The nucleus reverts/realigns to its normal state via emission of a photon, whose frequency is dependent on the energy difference between the normal and excited spin states. It is this motion that is used to construct a 3D image composed of information from the strata of the object; this depth information is obtained by transmitting multiple radio waves at differing frequencies in space [169].…”
