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.
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.
Technical Considerations in MR Angiography: An Image-Based
- 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
- 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
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.
