In magnetic resonance, a spin echo or Hahn echo is the refocusing of spin magnetisation by a pulse of resonant electromagnetic radiation. Modern nuclear... 15 KB (1,459 words) - 12:31, 5 January 2024 |
MRI pulse sequence (redirect from Turbo spin echo) spins are not coherent. When the spins are rephased, they become coherent, and thus signal (or "echo") is generated to form images. Unlike spin echo,... 30 KB (3,949 words) - 07:57, 6 May 2024 |
