Neck
General Hints
• Topogram: Lateral, 256 mm or AP 512 mm.
• Patient positioning
Patient lying in supine position, hyperextend neck
slightly, secure head well in head holder.
• Patient respiratory instruction:
do not breathe, do not swallow.
• For contrast studies, CARE Bolus (optional) may be
used to optimize the bolus timing.
• For image reconstruction of bone structure, use ker-
nel B60.
• Patient positioning is very important for artifact-free
images. The thoracic girdle should be positioned as
far as possible in the caudal direction. This can be
done using a strap with a permanent loop or Velcro
fastener at its end. The ends of the strap must be
attached to the patients wrists. Then the strap must
be wrapped around the patients feet with his legs
extended and under tension. The entire thoracic gir-
dle is thus pulled toward the patients feet.
