Reference Source	JHU Protocol
Scanner Used	64 Slice
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

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.
