Read chapter 5 of your textbook and answer the following questions (Print the answers and bring it to class on Wednesday).
Draw and label pulse sequence diagrams for each of the following (1-4):
1. Conventional Spin Echo
2. Dual Echo Spin Echo
3. Fast Spin Echo
4. Inversion Recovery
5. What parameters (TR and TE) would you use to produce T1 (t-one) weighting in a spin echo pulse sequence?
6. What do the initials ETL, and ETE stand for, what pulse sequence do they apply to, and give another term used instead of ETL?
7. What parameters (TR, TE and TI) would you use to achieve proton density weighting in Inversion recovery?
8. Give the main reasons for using a Short tau inversion recovery(STIR) sequence?
9. List two advantages and one disadvantage of a gradient rephased echo (GRE) sequence compared to a conventional spin echo sequence?
10. How does T2* differ from T2 weighting?
