SMRT Educational Seminars
 
MR Imaging Near Metal Implants
Volume 16, Number 3
 
Accreditation:
The SMRT Educational Seminars (Volume 16, Number 3), has been approved for 1.50 Category A Continuing Educational credits.

Read the SMRT Educational Seminars (Volume 16, Number 3), "MR Imaging Near Metal Implants" and complete the quiz.

To receive credit the quiz must be completed with a score of 75% or better. Completion of all questions with a passing score will earn a total of 1.5 category A Continuing Education credits. The certificate will state the CE reference number and awarded CE credits.

Members receiving a score less than 75% will be notified and given the option of taking the quiz up to two additional times.

Members should retain their CE Certificate for their Continuing Education registry requirements.

 
Educational Objectives
Magnetic Resonance Imaging Near Metal Implants
  • Review the background of metal implants and devices, and the MR imaging applications;
  • Describe the effect of the presence of metal on B0 homogeneity including different types of distortions;
  • Review the different methods of MR imaging used to alleviate the effects of the presence of metal;
  • Discuss post processing as a means to enable spatially accurate MRI near metal;
  • Explain recently developed imaging sequences specifically designed to reduce the effects of metal in MRI; and
  • Show image examples and comparisons of fast spin echo (FSE), slice encoding for metal artifact correction (SEMAC) and multi-acquisition variable-resonance image combination (MAVRIC).

New MR Imaging Methods for Metallic Implants in the Knee: Artifact Correction and Clinical Impact

  • Review the background of total knee replacements and the effect upon society;
  • Describe the use of recently developed MR imaging sequences specifically designed to address the effects of the presence of metal implants and devices;
  • Show image examples and comparisons of fast spin echo (FSE), slice encoding for metal artifact correction (SEMAC) and multi-acquisition variable-resonance image combination (MAVRIC) in the MR imaging of total and partial knee replacements;
  • Discuss the scan parameters used for each of the fast spin echo (FSE), slice encoding for metal artifact correction (SEMAC) and multi-acquisition variable-resonance image combination (MAVRIC) scans included in the study;
  • Explain statistical methods used to evaluate the imaging results; and
  • Review the different kinds of artifacts and distortions visualized in the MR images.
