CT EXTREMITY - UPPER

INDICATIONS: Trauma, fracture, dislocation, pain

PATIENT PREP: None

IV CONTRAST: Perform as directed by the supervising radiologist.

With:100 mL Isovue 370 @ 2.0 mL/second

WithOut;None

ORAL CONTRAST: None

POSITIONING: Head First Prone, Arms extended (Adapt to Patient/Part)

TOPOGRAMS: AP. Range: Through region of interest. 35 mA, 120 kV.

Lateral. Range: Through region of interest. 35 mA, 120 kV

SCAN TYPE: Spiral/Helical

NOTES: Scan in as close to Axial Plane as possible. Then do 2mm Reconstructions in Axial/Coronal/Sagittal planes angled to body part in question.

On the Recon Card use 3D Axial/Coronal/Sagittal to do this.

Send Thin Slice Volume Source Images: Recon #1 (0.6 x 0.6mm) to PACS.

Check if referring physician has specific orders.

ALARA – Keep radiation dose As Low As Reasonably Achievable.

*3D Only if Ordered by Referring Physician or requested by Radiologist. Obtain order for 3D from referring physician.

For 3D Only: Send Recon 0.6 x 0.3mm to Vital Workstation for 3D and call Spokane.
