| Notes: | Scan for 8-10 Seconds then begin contrast injection @ 5ml/s15ml Saline chaserASL 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 |
