To include the entire aortic vasculature
60 sec post arterial phase imaging
Aortic stent only
Scan Comments: Dual energy is useful for post processing applications such as bone removal and virtual non contrast. Utilizing these processing techniques it is possible to eliminate the noncontrast image acquisition phase when following up Aortic stent placement. All scans are performed using the ALARA principle.
100 / 140
Care Dose Reference mAs
250 / 193
Average Acquisition Time
10 - 15 sec
32 x 0.6mm
Comments: Images are acquired using 100 / 140 kVp setting with a SN filter. CareDose 4D is used to significantly reduce patient exposure. The pitch value should remain below 1.0 to reduce any artifacts during post processing.
Window Width and Level
Reconstruction Comments: When generating mixed images the DE composition is set to 0.8. Coronal and Sagittal images are also performed.
4-5ml / sec
Comments: Bolus Tracking is performed off the abdominal aorta using a 230 HU trigger setting. .
