One problem that can occur in MRI with materials having susceptibility artifacts, which can cause severe degradation, or more subtle effects that can lead to misinterpretation of the MR image. Another problem that occurs with such material is deflection in the magnetic field. The aim of this study was to develop an electromagnetic model to derive the susceptibility artifacts of the cool-tip RF needle in magnetic resonance imaging.
