MR Pfizer A392119 Research Protocol

Revised - 1/2015
Charge as Total Spine WO & Pelvis WO

What would Joe do? (WWJD)
  • This is a study of the spine and SI joints for Ankylosing Spondylitis. A marker needs to be placed on the patients’ back at the same level as the xiphoid process. The spine is done in two jumps. The two stacks for the total spine need to overlap covering the marker and cover from C1 through S2 (see Fig. 1). If unable to do in two jumps, can do in 3 jumps – change FOV to 300x300 (do not change any other parameters)
  • The entire exam is done with the 5CH CTL Spine Coil. Do not use the combo coil or switch to the torso coil for the pelvis.
  • For SI Joint Imaging – use the 3 plane loc/midline sag series to get a true mid-sag view of the sacrum. Angle to the posterior aspect of S2 vertebrae, centered A to P on S2 and the third slice of the stack runs along this posterior aspect. (see Fig. 2)
