Specific anatomic region	Neck
Application	R/O mass or nodes or abscess

Reference Source	JHU Protocol
Scanner Used	64 Slice
KV/Effective mAs/ Rotation time (sec)	120/ 200 / 1.0
Detector Collimation (mm)	0.6
Slice thickness (mm)	3mm and .75mm (for 3D)
Pitch	0.9
Kernel	B31f medium smotth + : Larynx window B70s very sharp : Head Bone window
Reconstruction interval	3mm x 3mm ST and Bone & .5mm (3D)
Image order (acquisition)	Cr-ca
Oral contrast	N/A
IV contrast volume and type	100-120 cc Omnipaque 350
Injection rate	3.0-2.5 cc/sec
Scan delay (sec)	Depends on patient, but in 30 sec range
3D technique used	N/A
Comment: If a mass is seen 3D mapping ca be done by reconstructing data at .75mm slice thickness and .5mm intervals. Scan delay of minimum 30 seconds is needed to visualize both carotid artery and jugular vein.
