SMRT Educational Seminars
Neuro MRI: Principles and Protocols
Volume 12, Number 2
The SMRT Educational Seminars (Volume 12, Number 2), has been approved for 3.0 Category A Continuing Educational credits.

Read the SMRT Educational Seminars (Volume 12, Number 2), "Neuro MRI: Principles and Protocols" 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
Neuro MR: Principles
  • Define changes in image contrast based on T1, T2, T2* and diffusion;
  • Discuss the specifics of T1- and T2-weighted image contrast;
  • Show examples of and explain pulse sequence timing diagrams;
  • Review the differences between spin echo and fast spin echo imaging;
  • Discuss image acquisition options including parallel imaging;
  • Define imaging sequences: acronyms, features and key variables;
  • Show examples and explain the use of gadolinium-based contrast agents in T1- and T2-weighted imaging, and as negative enhancement;
  • Discuss the rapid acquisition sequences and applications including BOLD, EPI, DWI and DTI; and
  • Review Magnetization Transfer Contrast technique and imaging at fields above 1.5T.
Neuro MR: Protocols
  • Review protocols and scan parameters for imaging of the brain including screening, MS, tumor, epilepsy, cerebrovascular, stroke;
  • Show examples of MR imaging and spectroscopy of the brain;
  • Discuss applications and imaging of the spine; and
  • Review the artifacts and pitfalls in imaging of the central nervous system (CNS).
Diffusion Imaging Concepts for Clinicians
  • Review the basic principles of diffusion, and its applications and imaging techniques;
  • Define and show examples of diffusion ellipsoid-eigenvectors/eigenvalues;
  • Discuss the calculation of ADC and its value;
  • Give examples of ADC in various pathologic conditions;
  • Review the measure and show examples of anisotropy; and
  • Define and show examples of tract tracing from diffusion data.
