Scanner UsedSiemens Somatom Plus 4
Injection Rate3cc/sec
Contrast Volume and Type150cc of Omnipaque 350
Area ScannedFrom level of celiac axis to below common iliac aa
Scan Delay (2 delays if dual spiral)30sec/60-70sec
Length of Spiral (time)35-40sec
Slice Thickness3mm
Table Speed/Pitch5-6mm/sec or pitch up to 2
Reconstruction Interval1mm for arterial phase 2mm for venous phase
3D Technique UsedVolume rendering with MIP in select instances as a complement
Comment: The technique is a dual-phase study with the arterial phase for arterial mapping and the venous phase for the renal vein and its variants. A delayed topogram (scoutview) is obtained to evaluate the pelvocalyceal system.
