magnetic resonance angiography
nuclear magnetic resonance
(physics) The absorption of electromagnetic radiation (radio waves), at a specific frequency, by an atomic nucleus placed in a strong magnetic field; used in spectroscopy and in magnetic resonance imaging.
magnetic resonance imaging
(medicine) A technique that uses nuclear magnetic resonance to form cross sectional images of the human body for diagnostic purposes.
nuclear quadrupole resonance
(physics, chemistry) A technique, related to nuclear magnetic resonance, that allows detection of transitions of atomic nuclei in the absence of a magnetic field.
electron spin resonance
(physics) The absorption of radiation by species having unpaired electrons when placed in a magnetic field that is used spectroscopically to detect and study free radicals
magnetic resonance tomography
electron spin resonances
microwave resonant cavity thruster
(physics, dynamics) A theoretical type of drive that does not conform to Newton's Laws of Motion, violating the conservation of momentum, using a resonant cavity where microwaves are beamed.
functional magnetic resonance imaging
(medicine) A form of magnetic resonance imaging that records the flow of blood to areas of the brain when the patient is undertaking a specific neural activity.
