| Scanner Used | GE HiSpeed Advantage |
| Injection Rate | 3-5ml/sec |
| Contrast Volume and Type | 150ml of Optiray 320 |
| Area Scanned | Entire liver |
| Scan Delay | Arterial phase (AP): 20secDelayed phase (DP): 60-70sec |
| Length of Spiral (time) | 20-30sec each |
| Slice Thickness | 7mm |
| Table Speed/Pitch | 7mm/sec |
| Reconstruction Interval | 7mm |
| 3D Technique Used | None |
| Comment: If the scanner can only obtain a single spiral scan then the arterial-phase study should be chosen as this is the best phase for lesion detection. Some sites will also do non contrast studies although we typically do not find it necessary. |
