Reference Source	JHU Protocol
Scanner Used	64 Slice
KV/Effective mAs/Rotation time (sec)	120/200/0.33
Detector Collimation (mm)	0.6
Slice Thickness (mm)	3 and 0.75
Pitch	0.75
Kernel	30
Reconstruction Interval	2 and .5
Image Order (acquisition)	Cr-ca
Oral Contrast	N/A
IV contrast volume and type	100 cc of Omnipaque-350
Injection Rate	3 cc/sec
Scan delay (sec)	25 and 45
3D technique used	VRT and MIP
Comment: AVMs can be recognized, even on non-contrast CTs, but with contrast the definition is obviously better. VRT and MIP are critical to detect even the small AVMs.
