Some fundamental technical aspects of magnetic resonance imaging (MRI) in evaluation of iron deposition were discussed. MRI is an imaging modality sensitive to iron deposition of the brain tissue. T2 weighted imaging (T2WI), T2* weighted imaging (T2*WI), and susceptibility-weighted imaging (SWI) are particularly available for this purpose. They are different in sensitivity and availability, and should be used in the right places respectively. Susceptibility to iron deposition is also dependent on the strength of static magnetic field, which should be taken into account in the interpretation of the images.
