Based on magnetic fields and pulsed radio frequencies without ionising radiation, it is a class of techniques that use the static or changing properties of polar molecules in the brain, such as haemoglobin, to visualise its structures, or activity in structures. Also used to estimate body composition, specifically images of fat, muscle and bone tissues.
