- Rad to assist with placing Spectroscopy voxels whenever possible.
Note for scanners MR3 and MR4 with compressed sense and 3D imaging:
3D imaging and compressed sense are much more susceptible to motion. If you have a patient that is unable to hold still for an exam after trying all of our other interventions (padding, medication, etc.), then you will need to revert to the old 2D protocols for optimal imaging results.

Scanner preference: MR3, MR4, DMR2, BEAVERTON. MR2 if patient has implant not safe for 3T.

|AXIAL||SWI||2D||2mm/-1mm||MR3 and MR4||-||20cm||-||Angle to Corpus. Cover skull base to vertex. Ok to add slices. Run Ven Bold on MR1 and MR2 instead of this sequence.|
|POWER INJECT CONTRAST|
|+DSC||Cover tumor. Do not add slices.||Injection Rate: 4-5mL/sec. Start injection 8-10 seconds after beginning the sequence. For peds patients with smaller IVs, consult with Rad and peds RN or Anesthesiologist to determine a safe injection rate.|

|+SAG||T1 fs||3D||-||MR3 and MR4||YES||23cm||YES||NO ANGLE. Cover ears.|
|AX||Label as +T1 FS ax. Angle to corpus. 1 skip 0.|
|SAG||Label as +T1 FS sag. Angle to midline. 2 skip 0. Cover ears.|
|COR||Label as +T1 FS cor. Angle to corpus. 2 skip 0. Cover nose.|
|Single Voxel Spectroscopy||Rad to place. Center on lesion. Avoid bone with placement in all 3 planes. Don't see a mass, call radiologist. For multiple masses: Pick the largest one remote from bone/fat/blood. If mass has rim enhancement, include some of rim that enhance in voxel.|
|Single Voxel Spectroscopy||Center on contralateral side in same general location as mass. Avoid bone.|
