SMRT Educational Seminars
Exploring Magnetic Field Strengths: Challenges and Opportunities
Volume 9, Number 3
The SMRT Educational Seminars (Volume 9, Number 3), has been approved for 3.0 Category A Continuing Educational credits.

Read the SMRT Educational Seminars (Volume 9, Number 3), "Exploring Magnetic Field Strengths: Challenges and Opportunities" and complete the quiz and official Answer Form at the back of the article. 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 3.0 category A Continuing Education credits.
SMRT members should send the completed Answer Form to the SMRT Education Department for scoring. 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 an additional two times. Members should retain their CE Certificate for their Continuing Education registry requirements.
Educational Objectives
  • To review the basic physics and principles of contrast resolution in MR images.
  • To understand the intrinsic properties and extrinsic parameters which affect contrast and signal-to-noise ratio (SNR) in MR images.
  • To describe operator selectable parameters that determine spatial resolution, SNR and scan time, and the trade-offs between.
  • To review various designs of radiofrequency (RF) coils appropriate for different magnetic field strengths and orientation of B0.
  • To describe the technical issues of utilizing higher magnetic field strengths at 3 T and beyond.
  • To understand the behavior of major generic pulse sequences as a function of field strength.
  • To identify the advantages and challenges of MR imaging of blood, blood flow and brain activation at higher field strengths.
  • To discuss specific issues, tips and techniques for imaging the body at 3 T.
  • To review the clinical advantages of MR imaging of the abdomen at 3 T.
