Diaphragm through lower extremities to include entire vasculature
Scan Comments: Dual energy is useful for post processing applications such as bone removal and virtual noncontrast. All scans are performed using the ALARA principle. A 3D Post Processing is performed with this protocol.
100 / 140
Care Dose Reference mAs
250 / 193
Average Acquisition Time
32 x 0.6mm
Comments: Images are acquired using 100 / 140 kVp setting with a SN filter. CareDose is used to reduce patient dose. The pitch value should remain below 1.0 to reduce any artifacts during post processing.
Q40f / B20f
Window Width and Level
|Reconstruction Comments: Additionally, a bone reconstruction is performed using 5 mm x 5 mm slices, a B70f algorithm, and a window width and level of 1776/176. When generating mixed images, the DE composition is set to 0.8. Coronal and sagittal image reconstructions are also performed. 3D MIP images are also performed.|
Comments: Bolus tracking is performed off the abdominal aorta using a 230 HU trigger setting. The injection rate should not exceed 5ml/sec. to protract the contrast bolus.
