- MT suppresses signal from neural tissue and from muscle tissue.
- We have been able to get excellent contrast and SNR from gradient
- recalled echoes by using MT with flip angles of about 50 deg or
- more. Without MT, we would have to keep the flip angles below 20
- deg to get good cord-to-CSF contrast on cervical spine exams.
- The lower flip angles reduce SNR.
-
- MT is clinically available in Resonex's application software.
