[Magnetography--a potential diagnostic method in the 21st century].
Electric currents in human body are generated by variations in membrane and action potentials. These bioelectric currents cause magnetic field which could be detected both inside and outside human body, on a certain distance. Measurements of biomagnetic fields are still at an experimental stage, but soon, with improvements in technology, they will become very important diagnostic tools, like registrations of surface electric potentials already are. Registration of magnetogram is performed without a direct contact of the probe and the surface, which enables measurements on the top of clothes, bandages and casts. Magnetic field probe can be easily moved from one part of the body to another, enabling so tracing of the observed signal. Similar mobility is not possible in electrography.
