Thorax
Hints in General
1. Topogram: AP, 512 mm.
2. Patient positioning:
Patient lying in supine position, arms positioned
comfortably above the head in the head-arm rest,
lower legs supported.
3. 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.
4. For image reconstruction of mediastinum,
use kernel B30.
5. For image reconstruction of the lung, use kernel B80.
6. If the voltage is lowered from 120 kV to 80 kV
significant higher mAs values have to be used
(at least by a factor of 2).
