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 | lung apices through the diaphragm to include the adrenal glands |
Venous Phase | N/A | N/A | N/A | N/A |
Delayed Phase | N/A | N/A | N/A | N/A |
Scan Comments: All scans are performed using the ALARA principle. |
Technical Parameters | Parameters |
kVp | 120 |
Effective mAs | 275 |
Time (Rotation) | 0.5 sec |
Average Acquisition Time | 8-10 sec |
Collimation | 64 x 0.6mm |
Pitch Value | 0.8 |
Scan Direction | craniocaudal |
Comments: The Effective mAs is adjusted based on a patient’s body habitus. In addition, dose reduction software could be used to limit patient dose with a quality reference mAs of 200. This would maintain image quality while lowering patient dose. |
