Scanner Used | Siemens Somatom Plus 4 |
Injection Rate | 3cc/sec |
Contrast Volume and Type | 120cc of Omnipaque-350 |
Area Scanned | From top of left hemidiaphragm through lower border of spleen (at least below celiac axis) |
Scan Delay | 30sec / 60sec (of dual study) |
Length of Spiral (time) | Usually 20-30sec |
Slice Thickness | 3mm |
Table Speed/Pitch | 3-5mm/sec |
Reconstruction Interval | 2-5mm (depends on clinical problem) |
3D Technique Used | Volume rendering for splenic aa and vein |
Comment: This describes a dual-phase technique which also optimizes evaluation of the splenic aa and vein. Single-phase techniques can be used in most cases with the delayed-phase images usually easier to interpret. |
