Specific Anatomic Region | Renal arteries |
Application | Renal artery stenosis evaluation |
Author | Galanski M et al. |
Reference Source | Radiology 1993; 189:185-192 |
Scanner Used | Siemens Somatom Plus or Plus-S |
Injection Rate | 3-5ml/sec (choice 3.5ml/sec) |
Contrast Volume and Type | 100-150ml of Iopromide-300 |
Area Scanned | Entire length of the kidneys |
Scan Delay | Test-dose timing (usually 20-30sec) |
Length of Spiral (time) | 32sec |
Slice Thickness | 2mm |
Table Speed/Pitch | 2mm/sec with a pitch of 1 |
Reconstruction Interval | 1-2mm |
3D Technique Used | Gradient shaded-surface rendering (with threshold of 130-220 HU) and MIP |
Comment: Test dosing to optimize timing was used in this study. This is similar to work by Rubin et al. but they inject at 5cc/sec. A key in these cases is to look for accessory renal arteries which increase the length of coverage needed. |
