MR Imaging and Cochlear Implants with Retained Internal Magnets: Reducing Artifacts near Highly Inhomogeneous Magnetic Fields is organized by Radiological Society of North America (RSNA).

Online Course Start Date: 1/10/2018
End Date for CME Eligibility/Online Expiration Date: 1/9/2021

Duration:
This journal-based CME activity is estimated to take 1 hour to complete.

Description :
The goal of the RadioGraphics articles designated as self-assessment CME features and their accompanying tests is to increase understanding of the radiologic characteristics and possible therapeutic options for a variety of pathologic conditions and basic physics principles.

Content Areas :
• Magnetic Resonance Imaging
• Neuroradiology
• Physics and Basic Science
• Safety & Quality

Objectives:
• Discuss the risks of proceeding with MR imaging for patients with a cochlear implant.
• Identify common MR imaging artifacts arising from cochlear implants with typical neuroimaging sequences.
• Describe strategies to reduce or shift artifacts from an anatomic region of interest.
