Injection Rate | 3 cc/sec | |
Contrast Volume and Type | 120 cc of Omnipaque-350 | |
Area Scanned | Top of left hemidiaphragm thru iliac crest | |
Scan Delay | Usually 45-50 sec but 30 sec delay for arterial phase imaging may be better | |
Length of Spiral (time) | 35 sec (approx.) | |
Slice Thickness | 3mm | |
Table Speed/Pitch | 5mm/sec or pitch of 1.6 | |
Reconstruction Interval | 2-3mm | |
3D Technique Used | Volume rendering in select cases | |
Comment: 1. The key to this protocol is the use of H2O to distend the stomach rather than a positive agent. We use 750cc of H2O. 2. Virtual endoscopy may be helpful in these cases. |
