MR Brain Tumor WWO Neuro Protocol

Scan notes:

  • If Stereotactic sequences are specifically requested: No headphones, light padding only per Frameless protocol
  • Note for MR3 and MR4 Scanners: 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

PROTOCOL FOR MR2 / MR3 / MR4 / DCH / BEAVERTON

Plane Weighting Mode SL/G CS FS FOV MPR Notes
AXIAL DWI SE EPI 3mm/0.3mm - SPIR 23cm - Angle to Corpus- Skull Base to Vertex
AXIAL T1 3D - MR3 and MR4 - 23cm YES NO ANGLE. Cover at least 1cm above vertex through skull base. Cover entire nose.
AX Label as T1 ax. Angle to corpus. 1 skip 0.
SAG Label as T1 sag. Angle to midline. 2 skip 0. Cover ears.
COR Label as T1 cor. Angle to corpus. 2 skip 0. Cover nose.
AXIAL T2 3D - MR3 and MR4 - 23cm YES NO ANGLE. Cover at least 1cm above vertex through skull base. Cover entire nose.
AX Label as T2 ax. Angle to corpus. 1 skip 0.
SAG Label as T2 sag. Angle to midline. 2 skip 0. Cover ears.
COR Label as T2 cor. Angle to corpus. 2 skip 0. Cover nose.
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.

AX Label as +T1 ax. Angle to corpus. 1 skip 0.
SAG Label as +T1 sag. Angle to midline. 2 skip 0. Cover ears.
COR Label as +T1 cor. Angle to corpus. 2 skip 0. Cover nose.
+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 corpus. 2 skip 0. Cover ears.
