A

Supine, Feet first, arms over head, knees bent

21
Q

Where is internal laser for L-spine

A

Xiphoid process (T9/10)

22

24
Q

Which type of recon shows better detail: 2D or 3D

A

2D

25
Q

What is the window for Spine soft tissue

A

350ww/50wl

26
Q

What is the window for spine bone

A

2000ww/500wl

27
Q

How long of a delay is recommended between intrathecal injection and scanning

A

1 to 3 hours so the CM has time to dilute

28
Q

What might happen if CM is too dense on our CT scan

Skull base to sacrum

32
Q

A

2 scans.
1: arterial scan
2: delayed scan immediately after first arterial scan

33
Q
