Notes:
  • Scan for 8-10 Seconds then begin contrast injection @ 5ml/s
  • 15ml Saline chaser
  • ASL Single Phase Slice Positioning. Place slices from top down.
COR FLAIR TSE 4mm 1mm None 23cm Frontal through Occipital Bone
SAGITTAL T1 flair
(T1 NOT T2 weighted).
High Resolution
TSE 3mm 0mm SPIR (mild) 16-18cm (ok to crop a few cm on either side); center over COW – MCAs. Be sure coverage includes the proximal COW to the MCA bifurcation on each side. Can reduce slices to around 24 to keep scan time under 7 minutes.
Turn flow compensation on

High Resolution
TSE 3mm 0mm SPIR (mild) 16-18cm Angle to Corpus – center over middle cerebral artery (MCA). Be sure coverage includes the proximal COW to the MCA bifurcation on each side. Can reduce slices to around 24 to keep scan time under 7 minutes.
