ANKLE

INDICATIONS: Trauma, fracture, dislocation

PATIENT PREP: None

IV CONTRAST: None

ORAL CONTRAST: None

POSITIONING: Feet First Supine (Adapt to Patient/Part)

TOPOGRAMS: AP & Lateral.

SCAN TYPE: Spiral/Helical

NOTES: Pitch 0.55 for Bone Micro-Detail

Pitch 0.80 for Bone Routine Detail

Pitch 0.80 for Soft Tissue Detail or exam With Contrast

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 0.75 x 0.7 mm) to Stentor.

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 #6 (0.75 x 0.4mm) to Vital Workstation for 3D and call Spokane.
