Specific anatomic region | Cardiac CTA |
Application | Test bolus |
Author | Elliot K Fishman, MD |
Reference Source | JHU Protocol |
Scanner Used | Siemens Sensation 64 |
KV/Effective mAs/ Rotation time (sec) | 120/ 40 / .5 |
Detector Collimation (mm) | 10 mm |
Slice thickness (mm) | 10 mm |
Pitch | N/A - 0 table feed |
Kernel | B20 |
Reconstruction interval | 10mm |
Image order (acquisition) | N/A |
Oral contrast | N/A |
IV contrast volume and type | Visipaque 320 20cc / 40cc Saline flush |
Injection rate | 4cc/sec |
Scan delay (sec) | 10 sec and then every 3 sec (10 scans) |
3D technique used | N/A |
Comment: Uses 2 sec cycle time. Test bolus used to determine patient specific delay time for CTA. Delay time + 6 sec is ideal. |
