Volume 14, Number 3 |
|
|
|
Accreditation: |
The SMRT Educational Seminars
(Volume 14, Number 3), has been approved for 2.5 Category A
Continuing Educational credits.
Read the SMRT Educational Seminars (Volume 14, Number 3),
"MR Imaging Physics Tutorial" 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 2.5 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 |
Fundamental Physics of MR Imaging
- Review the basic concepts including resonance and
precession.
- Describe radiofrequency energy, its absorption and the role
it plays in MRI.
- Discuss T1 and T2 relaxation and contrast including diagrams
and image examples.
- Explain the components of spin echo MR imaging using pulse
sequence diagrams.
- Review the effects of TE and TR and the resulting contrast
formation.
- Describe the variations of spin echo MR imaging including
multiecho, turbo, and inversion recovery.
- Introduce gradient echo MR imaging.
MR Imaging: Brief Overview and Emerging Applications
- Describe MR instrumentation including magnet designs, field
strength, and shim, gradient, and RF coils.
- Explain the process of MR signal localization used in image
reconstruction.
- Review gradients and their application used in localization
including slice-selection, frequency- and phase-encoding.
- Discuss MR signal in the form of T1 and T2.
- Introduce k-space and its formation and effect on MR images
generated.
- Describe parallel imaging and the initial variations.
- Discuss specific applications, basic and advanced, including
diffusion-weighted imaging and spectroscopy.
