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.
