| Scanner Used | Siemens Somatom Plus or Plus-4 |
| Injection Rate | 3ml/sec |
| Contrast Volume and Type | 120-150cc Omnipaque 350 |
| Area Scanned | Entire length of both kidneys |
| Scan Delay | 25sec |
| Length of Spiral (time) | 30-40sec |
| Slice Thickness | 2mm |
| Table Speed/Pitch | 3-4mm/sec |
| Reconstruction Interval | 1mm |
| 3D Technique Used | Volume rendering |
| Comment: This protocol covers both kidneys and so can evaluate multiple renal aa. A set of noncontrast scans are obtained to first define the area of interest. | |
