Haste and Rare sequences
Hi Elena,

you can find the different names for the same sequences and options used by manufacturers at: http://www.mr-tip.com/serv1.php?type=cam .

The manufacturers have in principle similar sequences with small differences. So, as you mentioned you can take "sequences as HASTE" or "sequences type RARE".
However, you can lead back these sequences also to the fundamental sequence type FSE ( fast spin echo: http://www.mr-tip.com/serv1.php?type=seq&sub=12 ). Fast sequences as HASTE ( http://www.mr-tip.com/serv1.php?type=db1&dbs=haste ) are especially useful in cases of movement caused by their single shot technique: http://www.mr-tip.com/serv1.php?type=db1&dbs=Single%20Shot%20Technique .

Hope this helps

shim system as normal

Then there should be a scout_silicone protocol.
tirm11_wss60b130.wlc TR 1530

If scout shows sillicone then use
tirm11_wss60b130.wlc TR 8568 4 mm cuts


If scout shows water only then use
tirm11_ss60b130.wlc TR 8568 4 mm cuts

The scout is :22 sec

The other sequences are 3:17
