Scanner Used Siemens Sensation 64
KV/Effective mAs/Rotation time (sec) 120/250/0.33
Detector Collimation (mm) 0.6
Slice Thickness (mm) 5 and .75
Pitch 0.7
Kernel 30
Reconstruction Interval 5 and .5
Image Order (acquisition) Cr-ca
Oral Contrast none
IV contrast volume and type 100-120 cc of Omnipaque-350
Injection Rate 3-4 cc/sec
Scan delay (sec) 25-30 sec
3D technique used VRT and MIP
Comment:Pre-set timing works well in these cases. In select cases, delayed scan (60-90 sec) may be useful if the arterial phase detects an aortic injury.
