- Discussion:
- T2 images have a long TR & long TE;
- used to distinguish normal from abnormal soft tissues;
- tissues w/ short T2 values include ca (cortical bone), ligaments & tendons;
- tissues w/ long T2 values include neoplasms, inflammation, & fluids;
- signal intensity of normal muscle is low to intermediate;
- longer TR (> 2000) and TE (> 85) will result in heavier T2 imaging;
- T2 in milliseconds is the time necessary to reduce transverse magnetization to 37% of its original value following the RF pulse
