Scanner Used | Siemens Sensation 64 |
KV/Effective mAs/Rotation time (sec) | 120/250/0.33 |
Detector Collimation (mm) | 0.6 |
Slice Thickness (mm) | 5 and .75 |
Pitch | 0.7 |
Kernel | 30 |
Reconstruction Interval | 5 and .5 |
Image Order (acquisition) | Cr-ca |
Oral Contrast | none |
IV contrast volume and type | 100-120 cc of Omnipaque-350 |
Injection Rate | 3-4 cc/sec |
Scan delay (sec) | 25-30 sec |
3D technique used | VRT and MIP |
Comment:Pre-set timing works well in these cases. In select cases, delayed scan (60-90 sec) may be useful if the arterial phase detects an aortic injury. |
