Padding Instructions:

  • If ordered WO/GAD: no padding on 3D T1

  • If ordered W/GAD: no padding on POST 3D T1

  • Use positioning sponges carefully at the level of the patient’s chin if needed. 

PADDING AND EARPLUGS MAY BE USED ON OTHER SEQUENCES IF PATIENT HAVING DIFFICULTY HOLDING STILL

  • If contrast if ordered, hand inject unless perfusion is requested.

  • Include additional air on top of scan for slice wrap.

If contrast is needed - hand Inject or power Inject if perfusion is requested.
