Thorax
Hints in General
• Topogram: AP, 512 mm.
• Patient positioning:
Patient lying in supine position, arms positioned
comfortably above the head in the head-arm rest,
lower legs supported.
• CARE Bolus may be used to optimize the bolus
timing.
Set the ROI for monitoring scan in the aorta at the
level of the diaphragm with triggering threshold of
120 HU, or use manual triggering.
• If the voltage is lowered from 130 kV to 110 kV
substantially higher mAs values have to be used
(at least by a factor of 2).
• To further optimize MPR image quality we recommend
that you reduce one or more of the following: colli-
mation, reconstruction increment, pitch factor while
using a wider slice width for image reconstruction.
