| 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 |
