07:00	Imaging Techniques & Challenges Bragi Sveinsson¹ ¹Stanford University MRI close to metallic implants is often desired to monitor and diagnose the tissue close to the metal. However, MRI close to such implants is difficult due to the metal’s interaction with the magnetic fields, which causes image artifacts. In recent years, powerful methods have been developed to overcome these artifacts. This talk will discuss how artifacts close to metal can be reduced, both by the choice of scan parameters and also by using advanced methods designed for artifact reduction.
07:25	Metal Related Artifacts: Imaging Techniques and Challenges Alissa Burge MRI is an excellent imaging modality for evaluation of a wide variety of pathologies, due to its combination of spatial resolution, tissue contrast, and sensitivity for edema. The utilization of MRI in the presence of metal, however, is complicated by a variety of associated artifacts, largely related to metal susceptibility. Though sometimes technically demanding, appropriate modification of pulse sequence acquisition parameters can mitigate the effects of metal related artifacts, and the utilization of more advanced metal reduction sequences, where necessary, can result in further reductions in artifact, yielding high quality diagnostic scans in patients with metallic implants.
