Scanner Used | Siemens Sensation 64 |
KV/Effective mAs/ Rotation time (sec) | 120 / 250/ 0.33 |
Detector Collimation (mm) | 0.6 |
Slice thickness (mm) | 0.75mm |
Pitch | 0.75 |
Kernel | 30 |
Reconstruction interval | 0.5mm |
Image order (acquisition) | Cr-ca |
Oral contrast | 1000 cc water 15-20 minutes prior to study |
IV contrast volume and type | 100-120 cc Omnipaque 350 |
Injection rate | 3-4cc/sec |
Scan delay (sec) | 25 sec (arterial)/ 60 sev (venous)/ 4-5 min (excretory) |
3D technique used | VRT & MIP |
Comment: The question is to maximize the information yet minimize the phases used. Non contrast is done with 5 mm thick sections at 5 mm intervals. The venous phase can be eliminated in many cases but an excretory phase is mandatory to exclude infection by TCC. |
