Trauma

Indication	Brief description	Slice thickness and reconstruction kernel	Further details of contrast timing/explanation of what the radiographers do	Abbreviation
Major trauma	CT head, neck, split bolus: chest, abdomen and pelvis	Neck 0.75 mm axial slices. Sagittal and coronal recons. Body and bone/lung: 1.5 mm with 1.2 mm increment. Sagittal and coronal recons.	60 ml contrast at 3 ml/s then 60 ml saline at 3 ml/s then 40 ml contrast at 4 ml/s then 40 ml saline at 3 ml/s Scan at 60 s post contrast	CT HNCAP + C
Bladder injury	CT cystogram, 50 ml water soluble contrast (300 mg/ml) in 500 ml water and instill ~350 ml via catheter, then clamp and scan	1.5 mm B30f, 1.2 mm increment.		CT Cystogram
Renal collecting system injury	When suspected following trauma scan, a delayed CT may be indicated. Ideally at time of scanning or if recognized later, later as a single phase.	1.5 mm B30f, 1.2 mm increment.	10 minute delay opacifies ureters	CT delayed phase/urographic phase abdo/pelvis
