1) To be aware that MR imaging is, a valuable tool in daily practice, for the assessment of patients with pain after placement of metal implants. 2) To review the several factors that reduce the severity of artifacts with large metal implants at MRI, in daily practice, including maximize the bandwidth used both during slice selection and during readout, use STIR imaging to avoid failure of fat suppression. 3) To learn about new techniques to reduce artifacts with large metal implants at MRI, including multiacquisition variable-resonance image combination (MAVRIC) method  

1)Principles of metal induced susceptibility artifacts with MRI. 2) Description of common ways to reduce or modify metal artifacts using common and available imaging techniques. 3) Description of new methods to correct readout-direction artifacts and slice-direction artifacts with metal such as multiacquisition variable-resonance image combination (MAVRIC) method. 4) Clinical experience with the technique
