MR Brain Tumor Follow Up WWO + Perfusion + Spectroscopy Neuro Protocol

Scan Notes

  •  PATIENT NEEDS A 20G OR BIGGER PERIPHERAL IV
  • Prep Power injector to split contrast injection for 2 injections:
  • DCE: Use 1/3 of the total contrast amount. Injection rate: 4-5ml/sec. Start injection AT THE SAME TIME YOU BEGIN Dynamic 8. 15ml Saline chaser
  • DSC: Use 2/3 of the total contrast amount. Injection Rate: 4-5mL/sec. Start injection 8-10 seconds after beginning the sequence.
  • Send to Pacs: DSC, DCE
  • Send to Intellispace: DSC, DCE, Post Ax T1
  • Post process: DSC only
  • Archive all sequences

Contrast injection

Plane Weighting Mode Slice Gap FAT SAT FOV Notes
DCE only available on 3T - - - - - Inject on 8th dynamic.1/3 total contrast amount.Injection rate: 4-5cc/sec. 15mL saline flush.Center through lesion of interest.Do not add slices.Post process in IntellispaceSend everything to PACS
DSC run on both 1.5T & 3T - - - - - Inject 8-10 seconds after dynamics begin.2/3 total contrast amount.Injection rate: 4-5cc/sec. 15mL saline flush.Cover lesion and as much brain tissue as possible.Do not add slices.Post process in IntellispaceSend everything to PACS

Single Voxel Spectroscopy 1cm3 Rad to place. Center on lesion. Avoid bone with placement in all 3 planes. Don't see a mass, call radiologist. multiple masses. Pick biggest one remote from bone/fat/blood. If mass has rim enhancement, include some of rim that enhance in voxel.
Single Voxel Spectroscopy 1cm3 Center on contralateral side in same general location as mass. Avoid bone.
