Acquisition Phase | Phase Included | Scan Delay | Respiration Phase | Anatomical Coverage |
Non Contrast | N/A | N/A | N/A | N/A |
Arterial Phase | Yes | bolus triggered | inspiration | scan range to the kidneys through the femoral heads |
Venous Phase | Yes | 60 sec | inspiration | scan range to include kidneys through iliac crest |
Delayed Phase | Yes | 5 min | inspiration | A low dose Topogram image is performed to visualize urinary collecting system |
Scan Comments: Scan ranges are limited to a specific area of interest to avoid unnecessary patient dose. All Scans are performed using the ALARA principle. |
Technical Parameters | Parameters |
kVp | 120 |
Effective mAs | 300 |
Time (Rotation) | 0.5 sec |
Average Acquisition Time | 10-12 sec |
Collimation | 64 x 0.6mm |
Pitch Value | 0.8 |
