Head
Hints in General
• Topogram: Lateral, 256 mm.
• Patient positioning:
Patient lying in supine position, arms resting against
body, secure head well in the head holder, support
lower legs.
• Gantry tilt is available for sequence scanning, not
for spiral scanning.
• For all head studies, it is very important for image
quality to position the patient in the center of the
scan field. Use the lateral laser beam to make sure
that the patient is positioned in the center.
• For image reconstruction of bone structure, use
kernel H60.
• In general, cerebrum studies with contrast medium,
except CTA and nasopharynx, can be performed
by hand injection. Start the scan after the injection is
completed.
