MTR images are not part of the protocol any more and SPGR series are added to it.

7 MS Climb study Thu, 5 Jan :45: Faria, Aida Bakshi R ( ) Hello, As per our conversation yesterday I have made the changes to the CLIMB PROTOCOL and the MS Brain protocol at 221 Longwood MRI. They are as follows: 3Plane Loc                                           :16 Sag 3D MP-RAGE                               7:42 Sag T2 Flair              18 slices             1:36 Ax SE T1                  54 slices             3:27        3/4 FOV Ax SE DE T2            54 slices            11:36 Contrast injection = by body weight - Ax T2 Flair post        28 slices              2:56 Ax DWI post            31 slices                :40 Ax SE T1 post         54 slices               3:27       3/4 FOV  5 minute delay post  contrast Total Gradient time:                            34:6 minutes 3Plane Loc                                                    :16 Asset Calc                                                    :12 Sag T2 Flair                       18 slices             1:36 Ax SE T1                           54 slices             4:20 Ax SE DE T2                      54 slices             9:12     3/4 FOV Contrast injection = by body weight Ax T2 Flair prop  post         28 slices              3:28 Ax DWI post                     31 slices                :40 Ax SE T1 post                  54 slices               4:20       5 minute delay post contrast Total Gradient time:                                      24:07 minutes
