Acquisition Phase | Phase Included | Scan Delay | Respiration Phase | Anatomical Coverage |
Non Contrast | Yes | N/A | N/A | Limited to area of interest |
Arterial Phase | N/A | N/A | N/A | N/A |
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. IV contrast may be useful if a soft tissue mass or abscess is being evaluated. |
Technical Parameters | Parameters |
kVp | 120 |
Effective mAs | 300 |
Care Dose Reference mAs | N/A |
Time (Rotation) | 1.0 sec |
Average Acquisition Time | 30-40 sec |
Collimation | 12 x 0.3mm |
Pitch Value | 0.8 |
Scan Direction | Craniocaudal |
Comments: The UHR protocol is used to improve spatial resolution and fine detail. The limitation is that the scan time is significantly longer when compared to using a larger collimator size. Dose reduction software can be used to limit patient exposure. |
Reconstruction Parameters | Bone | Thin Data | Soft Tissue |
Slice Thickness | 2mm | 0.4mm | 2mm |
Reconstruction Spacing | 2mm | 0.2mm | 2mm |
Reconstruction Algorithm | U90u | U70u | U30u |
Window Width and Level | 410 / 10 | 1776 / 176 | 410 / 10 |
Reconstruction Comments: Additionally a soft tissue thin data set is also performed using a 0.6mm x 0.4mm slices with an U30u algorithm. As a result of using the 12x0.3mm collimator the reconstructed field of view is limited to 30cm. |
Contrast Parameters | Parameters |
Contrast Type | Non Ionic |
Contrast Volume | 80ml |
Saline Flush | N/A |
Injection Rate | 2-3ml/sec |
Oral Contrast | N/A |
Contrast Volume | N/A |
Comments: IV contrast is not routinely necessary however if warranted we use the above protocol. |
