SMRT Educational Seminars
 
MR Angiography: Technical Considerations & Developments
Volume 16, Number 4
 
Accreditation:
The SMRT Educational Seminars (Volume 16, Number 4), has been approved for 2.0 Category A Continuing Educational credits.

Read the SMRT Educational Seminars (Volume 16, Number 4), "MR Angiography: Technical Considerations & Developments" 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 2.0 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
Technical Considerations in MR Angiography: An Image-Based Guide
  • Review Time-of-Flight principles including flow effects, 2D and 3D acquisition schemes, flip angle and TR effects, field strength effects and magnetization transfer; and show image examples;
  • Describe Phase-Contrast MRA including flow-encoding gradients; and show image examples;
  • Discuss Contrast-Enhanced MRA including bolus arrival and K-space, post-processing, dose reduction techniques; and show image examples;
  • Explain Nephrogenic Systemic Fibrosis (NSF), relaxivity of contrast media, and protein-binding agents; and
  • Describe parallel imaging techniques at 3T, dynamic imaging and balanced steady-state free precession; and show image examples.

Non-Contrast Enhanced MR Angiography: Physical Principles

  • Review the history of MR angiography techniques, non-contrast and contrast-enhanced methods;
  • Describe inflow-based techniques including the general mechanism and limitations, 3D TOF, HOP-MRA, 2D TOF, and QISS; and show image examples;
  • Discuss cardiac phase-dependent techniques including the general mechanism, and cardiac-gated 3D Fast-Spin-Echo NCE-MRA; and show image examples;
  • Explain flow-encoding techniques including the general mechanism, conventional phase contrast, 4D Flow, and flow-sensitive dephasing; and show image examples;
  • Review spin-labeling techniques including the general mechanism, Flow-In Spin Labeling, Flow-Out Spin Labeling, Tag-Alternation Spin Labeling; and show image examples; and
  • Describe relaxation-based techniques including the general mechanism and bSSFP.
