MRI: T2 Discussion

- 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
