PPT-MRI ARTIFACTS What are artifacts?

Artifacts are simply signal misrepresentations that do not correspond to the location of the specific tissue imaged What causes artifacts The Patient Subject Magnetic Field Inhomogeneity Machine Hardware.

Superconducting magnets use a special wire which loses all resistance when cooled to -270 degrees Centigrade. This requires liquid helium to surround the magnet wire. Current is applied to the wire during instillation, which generates the magnetic field as it flows. Superconducting magnets are normally FULLY ENERGIZED at all times..

Safety Background. The MRI scanner is a very large and powerful magnet. Most clinical scanners are 1.5 - 3 Tesla scanners. 3 Tesla = 30,000 gauss. Earths magnetic field ~ 0.5 gauss. MRI SAFETY. Magnetic Resonance Imaging (MRI) is one of the most powerful medical diagnostic technologies, combining strong magnetic fields with powerful computer image processing..
