CT — Umăr (MCB)

Updated 04/12/26 CT Shoulder Reviewed 04/12/26 Indications - trauma, fracture, dislocation, pain, bone tumor, soft tissue mass, infection, abscess, soft tissue gas, osteomyelitis, pre/post surgical evaluation. Bill under CT Shoulder charges. Arthrogram uses the with contrast charge. GENERAL SCAN NOTES Remove any metal from the imaging field of view. Topogram - from above top of shoulder to proximal humerus. Craniocaudal scan coverage - from above top of shoulder to proximal humerus (through prosthesis if present). Include entire ipsilateral scapula in FOV. Adjust FOV (field of view) on topogram to smallest without cropping anatomy. IV Contrast: 100 mL Omnipaque-300, inject at 2.5 mL/sec, 60 secs scan delay. For GE scanners, it is essential for the 1st recon thickness on the scanner to match the 1st recon thickness in this protocol book for the prescribed Noise Index to be valid. The 1st recon should generally be the thickest recon in the protocol. SIEMENS PARAMETERS & RECONS Scan
