Course Description:
Proper echo management is at the heart of every useful imaging
pulse sequence. This four-hour course will review the basics of
simple echo formation, study the problems encountered with refocusing
transverse magnetization, and discuss the theoretical and practical
means to assure well formed echoes. The course will build up from
simple pulse sequences to Fast Spin Echo imaging and fully refocused
SSFP imaging.
|
Audience Description:
This course is designed for graduate students, post-doctoral fellows
and residents with an interest in pulse sequence design, fast imaging
and body imaging. Participants should be familiar with k-space.
|
Educational Objectives:
Upon completion of this session, participants should be able to: |
Explain the basic principles of spin echo, gradient echo, and stimulated
echo formation;
Appreciate the
complexity of coherence pathways that arise when two or more RF pulses
are applied;
Describe methods
that investigators use to mitigate effects of multiple coherence
pathways to assure formation of proper echoes;
List techniques
used in steady-state free precession (SSFP) pulse sequences to minimize
spurious echo formation;
Determine which sequence will be appropriate for what
clinical application. |
