Content Areas (Codes):
The following Content Areas will be printed on the certificate for this course:

• Magnetic Resonance Imaging
• Physics and Basic Science

Learning Objectives:

• Distinguish basic aspects of MR Safety in the clinical environment, including how to avoid projectile incidents and manage patients with implanted devices.
• Distinguish the differences between MR Safe, MR Conditional, and MR Unsafe.
• Describe the origin of MR artifacts that commonly occur in clinical practice.
• Identify techniques to reduce or eliminate these artifacts.
• Review the basics of MR Siting and Acceptance testing.
• Review environmental factors such as vibration and moving metal. Review tests that can be performed after the MRI system is installed to verify its proper operation.
• Generate a general framework about essential elements of MR safety, to include a) risks associated with the main magnetic field, radiofrequency field, and time varying gradient fields; b) MRI zones I, II, III, IV; c) MRI safe, MRI conditional, and MRI unsafe device labeling; d) Quenches; e) Patient screening and ferromagnetic detection; and f) management of patients with implanted devices.
• Recognize common artifacts in MR images.
• Discuss the root cause of the artifacts.
• Describe the strategies to reduce or remove the artifacts.
• Describe environmental factors which may impact the site selection or planning, including potential sources of vibration and moving metal.
• Review a preliminary site layout for potential problems, including necessary support areas and access routes.
• Describe environmental and system tests that can be performed after the MRI system is installed to verify its proper operation.
