CT GUIDED JOINT INJECTION PROCEDURES PROCEDURE: Joint steroid and arthrogram injection procedures performed by the Radiologist using CT guidance. Shoulder, Hip, Knee, Elbow CT and MRI Arthrograms And/Or Steroid injections. Sacroiliac joint steroid injections. INDICATIONS: Pain, rotator cuff tear, labral tear, meniscus tear PATIENT PREP: None IV CONTRAST: None ORAL CONTRAST: None POSITIONING: Shoulder/Hip/Knee: Feet First Supine. Elbow: Head First Prone, Elbow Flexed. Adjust to region of interest. Sacroiliac: Feet First Prone. TOPOGRAMS: Shoulder/Hip - AP. Range: Through the region of interest according to performing Radiologist guidance. 35 mA, 120 kV. Elbow – Lateral. Range: Through the region of interest according to performing Radiologist guidance. 35 mA, 120 kV. Knee – AP and Lateral. Range: Through the region of interest according to performing Radiologist guidance. 35 mA, 120 kV. Sacroiliac - PA. Range: Through the region of interest according to performing Radiologist guidance. 35 mA, 120 kV. SCAN TYPE: Spiral/Helical NOTES: Shoulder/Hip/Elbow/Sacroiliac: Under Radiologist guidance perform a Control Scan at the level of interest. For Knee perform a Lateral Topogram instead. If necessary perform a short scan range with just a few slices above and below the level of interest. Using sterile technique assist the Radiologist with equipment and patient preparation. Once the procedure has begun, under guidance from the Radiologist perform short scan ranges through the region to check needle placement. ALARA – Keep radiation dose As Low As Reasonably Achievable.

*The operator must check the CTDIvol before and after the scan to ensure it is within the allowed dose range. Scans performed outside of the allowed range must be documented and reviewed by the designated radiologist and/or physicist. Shoulder, Hip and Sacroiliac: Allowed CTDIvol Dose Ranges: 0.5 mGy – 50 mGy XR29 Dose Notification Value (CTDIvol): 50 mGy Knee and Elbow: Allowed CTDIvol Dose Ranges: 0.5 mGy – 20 mGy XR29 Dose Notification Value (CTDIvol): 20 mGy
