KV/Effective mAs/ Rotation time (sec)	120 / 276/ 0.5
Detector Collimation (mm)	0.6
Slice thickness (mm)	3.0/5.0mm
Pitch	0.75
Kernel	30
Reconstruction interval	3.0-5.0mm
Image order (acquisition)	Cr-ca
Oral contrast	1000 cc water or Omnipaque-350 in water (100cc of Omnipaque-350 in one gallon of water)
IV contrast volume and type	100-120 cc Omnipaque 350
Injection rate	3cc/sec
Scan delay (sec)	60 sec
3D technique used	as needed
Comment: We will reconstruct with thinner slices and even do 3D reconstructions in select cases. This includes cases to define SMA/SMV as well as to exclude ischemia. CT angiography will require a different delay time and dual phase imaging. (25 & 50 sec).
