MR Brain Vasculitis WWO Neuro Protocol

Coverage on VWI:

  • If Philips: Oblique axial centered on COW, as in graphic below. F-H coverage 4.5-5.5 cm. Use MRA to plan placement of VWI sequence.
  • If Siemens: Sagittal centered on COW. L-R coverage ~ 13.5 cm.
  • Last updated: 9/26/2022
  • Charge as: Brain WWO & MRA Brain WO
  • Scanner preference: MR3, MR4, CHMR1. Only use 1.5T if implants.
  • Coil: Highest channel available for max SNR (64 on Siemens).
